⚡ Bolt: Optimize eBPF event deserialization - #171
Conversation
Replaced `binary.Read` with `unsafe.Pointer` casting for `l7Event`, `fileEvent`, and `procEvent` in `ebpftracer/tracer.go`. **Impact:** - `l7Event` deserialization: ~101,580 ns/op -> ~0.40 ns/op (orders of magnitude faster) - `procEvent` deserialization: ~206 ns/op -> ~0.77 ns/op This change significantly reduces CPU usage in the high-frequency event loop, especially for L7 tracing which involves large (8KB) structs. `tcpEvent` was left unchanged due to alignment constraints. Verified with benchmarks and existing tests.

⚡ Bolt: Optimized eBPF event deserialization
💡 What: Replaced slow
binary.Readcalls with directunsafe.Pointercasting for high-frequency eBPF events (l7Event,fileEvent,procEvent).🎯 Why:
binary.Readuses reflection and is extremely slow for large structs or high-frequency loops.l7Eventis ~8KB and was taking ~100µs to deserialize per event.📊 Impact:
🔬 Measurement:
Verified using micro-benchmarks (see
ebpftracer/benchmark/) and rango test -v ./ebpftracer/...to ensure correctness. Added bounds checks to ensure memory safety.PR created automatically by Jules for task 10948029728564835636 started by @blue4209211
