+# Memory Usage Benchmarks
+
+Benchmarks for measuring memory consumption of the Horus stack components.
+
+## Overview
+
+The memory benchmarks measure heap memory usage for various operations:
+- Job creation and storage
+- Client instantiation
+- Payload size impact
+- Memory growth under load
+
+## Benchmarks
+
+### 1. `memory_job_creation`
+Measures memory usage when creating multiple Job objects in memory.
+
+**Test sizes**: 10, 50, 100, 200 jobs
+
+**What it measures**:
+- Memory allocated per job object
+- Heap growth with increasing job count
+- Memory efficiency of Job structure
+
+**Expected results**:
+- Linear memory growth with job count
+- ~1-2 KB per job object (depending on payload)
+
+### 2. `memory_client_creation`
+Measures memory overhead of creating multiple Supervisor client instances.
+
+**Test sizes**: 1, 10, 50, 100 clients
+
+**What it measures**:
+- Memory per client instance
+- Connection pool overhead
+- HTTP client memory footprint
+
+**Expected results**:
+- ~10-50 KB per client instance
+- Includes HTTP client, connection pools, and buffers
+
+### 3. `memory_payload_sizes`
+Measures memory usage with different payload sizes.
+
+**Test sizes**: 1KB, 10KB, 100KB, 1MB payloads
+
+**What it measures**:
+- Memory overhead of JSON serialization
+- String allocation costs
+- Payload storage efficiency
+
+**Expected results**:
+- Memory usage should scale linearly with payload size
+- Small overhead for JSON structure (~5-10%)
+
+## Running Memory Benchmarks
+
+```bash
+# Run all memory benchmarks
+cargo bench --bench memory_usage
+
+# Run specific memory test
+cargo bench --bench memory_usage -- memory_job_creation
+
+# Run with verbose output to see memory deltas
+cargo bench --bench memory_usage -- --verbose
+```
+
+## Interpreting Results
+
+The benchmarks print memory deltas to stderr during execution:
+
+```
+Memory delta for 100 jobs: 156 KB
+Memory delta for 50 clients: 2048 KB
+Memory delta for 100KB payload: 105 KB
+```
+
+### Memory Delta Interpretation
+
+- **Positive delta**: Memory was allocated during the operation
+- **Zero delta**: No significant memory change (may be reusing existing allocations)
+- **Negative delta**: Memory was freed (garbage collection, deallocations)
+
+### Platform Differences
+
+**macOS**: Uses `ps` command to read RSS (Resident Set Size)
+**Linux**: Reads `/proc/self/status` for VmRSS
+
+RSS includes:
+- Heap allocations
+- Stack memory
+- Shared libraries (mapped into process)
+- Memory-mapped files
+
+## Limitations
+
+1. **Granularity**: OS-level memory reporting may not capture small allocations
+2. **Timing**: Memory measurements happen before/after operations, not continuously
+3. **GC effects**: Rust's allocator may not immediately release memory to OS
+4. **Shared memory**: RSS includes shared library memory
+
+## Best Practices
+
+### For Accurate Measurements
+
+1. **Run multiple iterations**: Criterion handles this automatically
+2. **Warm up**: First iterations may show higher memory due to lazy initialization
+3. **Isolate tests**: Run memory benchmarks separately from performance benchmarks
+4. **Monitor trends**: Compare results over time, not absolute values
+
+### Memory Optimization Tips
+
+If benchmarks show high memory usage:
+
+1. **Check payload sizes**: Large payloads consume proportional memory
+2. **Limit concurrent operations**: Too many simultaneous jobs/clients increase memory
+3. **Review data structures**: Ensure efficient serialization
+4. **Profile with tools**: Use `heaptrack` (Linux) or `instruments` (macOS) for detailed analysis
+
+## Advanced Profiling
+
+For detailed memory profiling beyond these benchmarks:
+
+### macOS
+```bash
+# Use Instruments
+instruments -t Allocations -D memory_trace.trace ./target/release/horus
+
+# Use heap profiler
+cargo install cargo-instruments
+cargo instruments --bench memory_usage --template Allocations
+```
+
+### Linux
+```bash
+# Use Valgrind massif
+valgrind --tool=massif --massif-out-file=massif.out \
+    ./target/release/deps/memory_usage-*
+
+# Visualize with massif-visualizer
+massif-visualizer massif.out
+
+# Use heaptrack
+heaptrack ./target/release/deps/memory_usage-*
+heaptrack_gui heaptrack.memory_usage.*.gz
+```
+
+### Cross-platform
+```bash
+# Use dhat (heap profiler)
+cargo install dhat
+# Add dhat to your benchmark and run
+cargo bench --bench memory_usage --features dhat-heap
+```
+
+## Continuous Monitoring
+
+Integrate memory benchmarks into CI/CD:
+
+```bash
+# Run and save baseline
+cargo bench --bench memory_usage -- --save-baseline memory-main
+
+# Compare in PR
+cargo bench --bench memory_usage -- --baseline memory-main
+
+# Fail if memory usage increases >10%
+# (requires custom scripting to parse Criterion output)
+```
+
+## Troubleshooting
+
+### "Memory delta is always 0"
+- OS may not update RSS immediately
+- Allocations might be too small to measure
+- Try increasing iteration count or operation size
+
+### "Memory keeps growing"
+- Check for memory leaks
+- Verify objects are being dropped
+- Use `cargo clippy` to find potential issues
+
+### "Results are inconsistent"
+- Other processes may be affecting measurements
+- Run benchmarks on idle system
+- Increase sample size in benchmark code
+
+## Example Output
+
+```
+memory_job_creation/10  time:   [45.2 µs 46.1 µs 47.3 µs]
+Memory delta for 10 jobs: 24 KB
+
+memory_job_creation/50  time:   [198.4 µs 201.2 µs 204.8 µs]
+Memory delta for 50 jobs: 98 KB
+
+memory_job_creation/100 time:   [387.6 µs 392.1 µs 397.4 µs]
+Memory delta for 100 jobs: 187 KB
+
+memory_client_creation/1    time:   [234.5 µs 238.2 µs 242.6 µs]
+Memory delta for 1 clients: 45 KB
+
+memory_payload_sizes/1KB    time:   [12.3 µs 12.6 µs 13.0 µs]

+    // ...
+}
+```
+
+## CI/CD Integration
+
+To run benchmarks in CI without the full stack:
+
+```bash
+# Run only fast benchmarks
+cargo bench --bench horus_stack -- --quick
+
+# Save baseline for comparison
+cargo bench --bench horus_stack -- --save-baseline main
+
+# Compare against baseline
+cargo bench --bench horus_stack -- --baseline main
+```
+
+## Troubleshooting
+
+### "Connection refused" errors
+- Ensure the Horus stack is running
+- Check that all services are listening on expected ports
+- Verify firewall settings
+
+### "Job execution timeout" errors
+- Increase timeout values in benchmark code
+- Check that runners are properly registered
+- Verify Redis is accessible
+
+### Inconsistent results
+- Close other applications to reduce system load
+- Run benchmarks multiple times for statistical significance
+- Use `--warm-up-time` flag to increase warm-up period
+
+## Adding New Benchmarks
+
+To add a new benchmark:
+
+1. Create a new function in `benches/horus_stack.rs`:
+```rust
+fn bench_my_feature(c: &mut Criterion) {
+    let rt = create_runtime();
+    let client = /* create client */;
+    
+    c.bench_function("my_feature", |b| {
+        b.to_async(&rt).iter(|| async {
+            // Your benchmark code
+        });
+    });
+}
+```
+
+2. Add to the criterion_group:
+```rust
+criterion_group!(
+    benches,
+    // ... existing benchmarks
+    bench_my_feature,
+);
+```

+# Start Redis
+redis-server
+
+# Start Horus (with auto port cleanup)
+RUST_LOG=info ./target/release/horus all --admin-secret SECRET --kill-ports
+```
+
+### Configuration
+
+All benchmarks use these defaults (configurable in source):
+- Supervisor: `http://127.0.0.1:3030`
+- Osiris: `http://127.0.0.1:8081`
+- Coordinator HTTP: `http://127.0.0.1:9652`
+- Coordinator WS: `ws://127.0.0.1:9653`
+- Admin secret: `SECRET`
+
+### Results
+
+Results are saved to `target/criterion/` with:
+- HTML reports with graphs and statistics
+- JSON data for programmatic analysis
+- Historical comparison with previous runs
+- Detailed performance metrics (mean, median, std dev, throughput)
+
+### Integration
+
+The benchmarks are integrated into the workspace:
+- Added to `Cargo.toml` with proper dependencies
+- Uses workspace-level dependencies for consistency
+- Configured with `harness = false` for Criterion
+- Includes all necessary dev-dependencies
+
+### Next Steps
+
+1. Run benchmarks to establish baseline performance
+2. Monitor performance over time as code changes
+3. Use stress tests to identify bottlenecks
+4. Customize benchmarks for specific use cases
+5. Integrate into CI/CD for automated performance tracking
+
+## Technical Details
+
+### Dependencies Added
+- `criterion` v0.5 with async_tokio and html_reports features
+- `osiris-client` from workspace
+- `reqwest` v0.12 with json feature
+- `serde_json`, `uuid`, `chrono` from workspace
+
+### Benchmark Harness
+Uses Criterion.rs for:
+- Statistical analysis
+- Historical comparison
+- HTML report generation
+- Configurable sample sizes
+- Warm-up periods
+- Outlier detection
+
+### Job Creation
+Helper function `create_test_job()` creates properly structured Job instances:
+- Unique UUIDs for each job
+- Proper timestamps
+- JSON-serialized payloads
+- Empty signatures (for testing)
+- Configurable runner and command
+
+This ensures benchmarks test realistic job structures that match production usage.
