+## Load Testing
+
+The bundle includes comprehensive load testing capabilities using k6. The k6 runner is built as a Go-based image (no Node.js required) from `docker/k6-go/Dockerfile`:
+
+```bash
+# Quick smoke test
+make k6-smoke
+
+# Run all load tests
+make k6-all
+
+# Stress test (31 minutes)
+make k6-stress
+```
+
+Notes:
+- The `k6` service is gated behind the `loadtest` compose profile. You can run tests with: `docker-compose --profile loadtest run k6 run /scripts/smoke-test.js`.
+- Dockerfiles are consolidated under the `docker/` directory, e.g. `docker/php.grpc.Dockerfile` for the PHP app and `docker/k6-go/Dockerfile` for the k6 runner.
+
+See [Load Testing Guide](loadTesting/README.md) for detailed documentation on all available tests and usage options.
+
## Usage
For detailed usage instructions, see [Testing Guide](docs/testing.md).

+# Benchmarks
+
+This document describes how to measure the overhead of the Symfony OpenTelemetry Bundle and provides a ready-to-run
+PhpBench configuration and sample benchmark.
+
+## What we measure
+
+We focus on βoverhead per HTTP requestβ for three scenarios:
+
+- Symfony app baseline (bundle disabled)
+- Bundle enabled with HTTP/protobuf exporter
+- Bundle enabled with gRPC exporter
+
+Each scenario is measured as wall-time and memory overhead around a simulated request lifecycle (REQUEST β TERMINATE),
+without network variance (exporters can be stubbed or use an in-memory processor).
+

+Notes:
+
+- Replace these numbers with your environmentβs measurements. Network/exporter configuration affects results.
+
+## How to run
+
+1) Install PhpBench (dev):
+
+```bash
+composer require --dev phpbench/phpbench
+```
+
+2) Run benchmarks:
+
+```bash
+./vendor/bin/phpbench run benchmarks --report=aggregate
+```
+
+3) Toggle scenarios:
+
+- Disable bundle globally:
+ ```bash
+ export OTEL_ENABLED=0
+ ```
+- Enable bundle and choose transport via env vars (see README Transport Configuration):
+ ```bash
+ export OTEL_ENABLED=1
+ export OTEL_TRACES_EXPORTER=otlp
+ export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf # or grpc
+ ```
+
+## Bench scaffold
+
+- `benchmarks/phpbench.json` β PhpBench configuration
+- `benchmarks/BundleOverheadBench.php` β benchmarks for collect and send traces and spans to collectors
+
+## Tips
+
+- Pin CPU governor to performance mode for consistent results
+- Run multiple iterations and discard outliers
+- Use Docker `--cpuset-cpus` and limit background noise
+- For gRPC exporter, ensure the extension is prebuilt in your image to avoid installation overhead during runs

+# Load Testing with k6
+
+This directory contains comprehensive k6 load testing scripts for the Symfony OpenTelemetry Bundle test application.
+
+## Overview
+
+k6 is a modern load testing tool. Test scripts are written in JavaScript and executed by the k6 runtime inside a Docker container.
+
+**Key Features:**
+- β
Containerized runner (docker/k6-go/Dockerfile)
+- β
Recent k6 version with core features
+- β
Extensible via xk6 (k6 extensions)
+- β
Minimal Docker image size
+- β
Comprehensive test coverage for all endpoints
+- β
Advanced scenario-based testing
+
+## Prerequisites
+
+- Docker and Docker Compose installed
+- The test application must be running (`docker-compose up` or `make up`)
+- k6 service is built from `docker/k6-go/Dockerfile`
+- PHP app runs in Docker container defined in `docker/php/`
+
+## Test App Endpoints
+
+The test application provides the following endpoints for load testing:
+
+| Endpoint | Description | Expected Response Time |
+|----------|-------------|------------------------|
+| `/` | Homepage with documentation | < 100ms |
+| `/api/test` | Basic API endpoint | < 200ms |
+| `/api/slow` | Slow operation (2s sleep) | ~2000ms |
+| `/api/nested` | Nested spans (DB + API simulation) | ~800ms |
+| `/api/pdo-test` | PDO query test (SQLite in-memory) | < 200ms |
+| `/api/cqrs-test` | CQRS pattern (QueryBus + CommandBus) | < 200ms |
+| `/api/exception-test` | Exception handling test | N/A (throws exception) |
+
+## Available Tests
+
+### 1. Smoke Test (`smoke-test.js`)
+**Purpose:** Minimal load test to verify all endpoints are working correctly.
+- **Virtual Users (VUs):** 1
+- **Duration:** 1 minute
+- **Use Case:** Quick sanity check before running larger tests
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/smoke-test.js
+```
+
+### 2. Basic Test (`basic-test.js`)
+**Purpose:** Test the simple `/api/test` endpoint with ramping load.
+- **Stages:**
+ - Ramp up to 10 VUs over 30s
+ - Maintain 20 VUs for 1m
+ - Spike to 50 VUs for 30s
+ - Ramp down to 20 VUs for 1m
+ - Cool down to 0 over 30s
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/basic-test.js
+```
+
+### 3. Slow Endpoint Test (`slow-endpoint-test.js`)
+**Purpose:** Test the `/api/slow` endpoint which simulates a 2-second operation.
+- **Stages:** Lighter load (5-10 VUs) to account for slow responses
+- **Thresholds:** p95 < 3s, p99 < 5s
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/slow-endpoint-test.js
+```
+
+### 4. Nested Spans Test (`nested-spans-test.js`)
+**Purpose:** Test the `/api/nested` endpoint which creates nested OpenTelemetry spans.
+- **Tests:** Database simulation + External API call simulation
+- **Duration:** ~800ms per request
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/nested-spans-test.js
+```
+
+### 5. PDO Test (`pdo-test.js`)
+**Purpose:** Test the `/api/pdo-test` endpoint with PDO instrumentation.
+- **Tests:** SQLite in-memory database queries
+- **Verifies:** ExampleHookInstrumentation functionality
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/pdo-test.js
+```
+
+### 6. CQRS Test (`cqrs-test.js`)
+**Purpose:** Test the `/api/cqrs-test` endpoint with CQRS pattern.
+- **Tests:** QueryBus and CommandBus with middleware tracing
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/cqrs-test.js
+```
+
+### 7. Comprehensive Test (`comprehensive-test.js`)
+**Purpose:** Test all endpoints with weighted distribution.
+- **Distribution:**
+ - `/api/test`: 40%
+ - `/api/nested`: 30%
+ - `/api/pdo-test`: 20%
+ - `/api/cqrs-test`: 10%
+- **Use Case:** Realistic mixed workload
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/comprehensive-test.js
+```
+
+### 8. Stress Test (`stress-test.js`)
+**Purpose:** Push the system beyond normal operating capacity.
+- **Stages:**
+ - Ramp to 100 VUs (2m)
+ - Maintain 100 VUs (5m)
+ - Ramp to 200 VUs (2m)
+ - Maintain 200 VUs (5m)
+ - Ramp to 300 VUs (2m)
+ - Maintain 300 VUs (5m)
+ - Cool down (10m)
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/stress-test.js
+```
+
+### 8. All Scenarios Test (`all-scenarios-test.js`) β RECOMMENDED
+**Purpose:** Run all test scenarios in a single comprehensive test with parallel execution.
+- **Duration:** ~16 minutes
+- **Execution:** Uses k6 scenarios feature for parallel execution with staggered starts
+- **Use Case:** Complete system validation and comprehensive trace generation
+- **Benefits:**
+ - π― Production-realistic load patterns
+ - π All features tested simultaneously
+ - π Comprehensive trace data for analysis
+ - β±οΈ Time-efficient compared to running tests individually
+ - π Scenario-specific thresholds and tags
+
+**Run:**
+```bash
+docker-compose run --rm k6 run /scripts/all-scenarios-test.js
+# or using Make
+make k6-all-scenarios
+```
+
+**Execution Schedule:**
+1. **0m-1m:** Smoke test (1 VU) - Validates all endpoints
+2. **1m-4m30s:** Basic load test - Ramping 0β50 VUs on /api/test
+3. **4m30s-6m30s:** Nested spans test - 10 VUs testing complex traces
+4. **6m30s-8m30s:** PDO test - 10 VUs testing database instrumentation
+5. **8m30s-10m30s:** CQRS test - 10 VUs testing QueryBus/CommandBus
+6. **10m30s-12m30s:** Slow endpoint test - Ramping 0β10 VUs on slow operations
+7. **12m30s-16m:** Comprehensive test - Mixed workload with weighted distribution
+
+**Scenario-Specific Metrics:**
+- Tagged metrics allow analysis per scenario type
+- Individual thresholds for each test type
+- Comprehensive failure rate monitoring
+
+## Running Tests
+
+### Quick Start
+
+1. **Start the application:**
+ ```bash
+ docker-compose up -d
+ # or using Make
+ make up
+ ```
+
+2. **Run a test:**
+ ```bash
+ # Run individual test
+ docker-compose run --rm k6 run /scripts/smoke-test.js
+
+ # Run all scenarios at once (recommended)
+ docker-compose run --rm k6 run /scripts/all-scenarios-test.js
+ # or using Make
+ make k6-all-scenarios
+ ```
+
+3. **View results in Grafana:**
+ ```
+ http://localhost:3000
+ Navigate to Explore > Tempo
+ # or using Make
+ make grafana
+ ```
+
+### Using Make Commands (Recommended)
+
+The project includes convenient Make commands for running k6 tests:
+
+```bash
+# Individual tests
+make k6-smoke # Quick sanity check
+make k6-basic # Basic load test
+make k6-slow # Slow endpoint test
+make k6-nested # Nested spans test
+make k6-pdo # PDO instrumentation test
+make k6-cqrs # CQRS pattern test
+make k6-comprehensive # Mixed workload test
+make k6-stress # Stress test (~31 minutes)
+
+# Run all scenarios in one comprehensive test
+make k6-all-scenarios # All scenarios test (~15 minutes) β RECOMMENDED
+
+# Run all tests individually in sequence
+make k6-all # Run all tests except stress test
+
+# Custom test
+make k6-custom TEST=your-test.js
+```
+
+### Using Docker Compose
+
+The k6 service is configured with the `loadtest` profile:
+
+```bash
+# Run specific test
+docker-compose --profile loadtest run k6 run /scripts/basic-test.js
+
+# Run without profile (if k6 is always available)
+docker-compose run --rm k6 run /scripts/basic-test.js
+
+# Run with custom options
+docker-compose run --rm k6 run /scripts/basic-test.js --vus 20 --duration 2m
+
+# Run with output to file
+docker-compose run --rm k6 run /scripts/basic-test.js --out json=/scripts/results.json
+
+# Run with environment variable override
+docker-compose run --rm -e BASE_URL=http://localhost:8080 k6 run /scripts/basic-test.js
+```
+
+### Running Without Docker
+
+If you have k6 installed locally:
+
+```bash
+cd loadTesting
+BASE_URL=http://localhost:8080 k6 run basic-test.js
+```
+
+## Test Configuration
+
+All tests share common configuration from `config.js`:
+
+### Default Thresholds
+- **http_req_duration:** p95 < 500ms, p99 < 1000ms
+- **http_req_failed:** < 1% failure rate
+- **http_reqs:** > 10 requests/second
+
+### Available Options
+- `options` - Default ramping load test
+- `smokingOptions` - Minimal 1 VU test
+- `loadOptions` - Standard load test (100 VUs for 5m)
+- `stressOptions` - Stress test up to 300 VUs
+- `spikeOptions` - Spike test to 1400 VUs
+
+## Viewing Results
+
+### During Test Execution
+k6 provides real-time console output showing:
+- Current VUs
+- Request rate
+- Response times (min/avg/max/p90/p95)
+- Check pass rates
+
+### In Grafana
+1. Open http://localhost:3000
+2. Go to Explore > Tempo
+3. Search for traces during your test period
+4. View detailed span information including:
+ - Request duration
+ - Nested spans
+ - Custom attributes
+ - Events and errors
+
+### Export Results
+```bash
+# JSON output
+docker-compose run --rm k6 run /scripts/basic-test.js --out json=/scripts/results.json
+
+# CSV output
+docker-compose run --rm k6 run /scripts/basic-test.js --out csv=/scripts/results.csv
+
+# InfluxDB (if configured)
+docker-compose run --rm k6 run /scripts/basic-test.js --out influxdb=http://influxdb:8086/k6
+```
+
+## Custom Test Configuration
+
+You can override configuration via environment variables:
+
+```bash
+# Change base URL
+docker-compose run --rm -e BASE_URL=http://custom-host:8080 k6 run /scripts/basic-test.js
+
+# Run with custom VUs and duration
+docker-compose run --rm k6 run /scripts/basic-test.js --vus 50 --duration 5m
+```
+
+## Interpreting Results
+
+### Success Criteria
+- All checks pass (status 200, response times within limits)
+- Error rate < 1%
+- p95 response times within thresholds
+- No crashes or exceptions in the application
+
+### Common Issues
+- **High response times:** May indicate performance bottleneck
+- **Failed requests:** Check application logs
+- **Timeouts:** Increase thresholds or reduce load
+- **Memory issues:** Monitor container resources
+
+## Best Practices
+
+1. **Start Small:** Always run smoke test first
+2. **Ramp Gradually:** Use staged load increase
+3. **Monitor Resources:** Watch CPU, memory, network
+4. **Check Traces:** Verify traces are being generated correctly in Grafana
+5. **Baseline First:** Establish baseline performance before changes
+6. **Clean Environment:** Ensure consistent test conditions
+
+## Troubleshooting
+
+### Tests Fail to Connect
+```bash
+# Verify php-app is running
+docker-compose ps
+
+# Check network connectivity
+docker-compose exec k6 wget -O- http://php-app:8080/
+```
+
+### No Traces in Grafana
+- Verify OTEL configuration in docker-compose.override.yml
+- Check Tempo logs: `docker-compose logs tempo`
+- Ensure traces are being exported: `docker-compose logs php-app`
+
+### High Error Rates
+- Check application logs: `docker-compose logs php-app`
+- Reduce concurrent users
+- Increase sleep times between requests
+
+## Advanced Usage
+
+### Custom Scenarios
+Create your own test by copying an existing script and modifying:
+```javascript
+import http from 'k6/http';
+import { check, sleep } from 'k6';
+import { BASE_URL } from './config.js';
+
+export const options = {
+ vus: 10,
+ duration: '1m',
+};
+
+export default function () {
+ const res = http.get(`${BASE_URL}/your-endpoint`);
+ check(res, { 'status is 200': (r) => r.status === 200 });
+ sleep(1);
+}
+```
+
+### Running Multiple Tests
+```bash
+#!/bin/bash
+for test in smoke-test basic-test nested-spans-test; do
+ echo "Running $test..."
+ docker-compose run --rm k6 run /scripts/${test}.js
+ sleep 10
+done
+```
+
+## k6 Architecture (Go-based)
+
+Our setup uses a custom Go-based k6 build:
+
+```
+βββββββββββββββββββββββββββββββββββββββ
+β docker/k6-go/Dockerfile β
+βββββββββββββββββββββββββββββββββββββββ€
+β Stage 1: Builder (golang:1.22) β
+β - Clone k6 from GitHub β
