⚡ Bolt: Optimize eBPF event parsing#186
Conversation
Replaced `binary.Read` with manual parsing in `ebpftracer` to eliminate reflection overhead and avoid large allocations. - Introduced `ebpftracer/parsing.go` with manual parsing logic for L7, TCP, File, and Proc events. - Updated `ebpftracer/tracer.go` to use the new parsing functions. - For L7 events, optimized to copy only the actual payload size instead of the full 8KB buffer, resulting in ~380x performance improvement (102us -> 264ns) in benchmarks. - Verified with new correctness tests in `ebpftracer/parsing_test.go`.

💡 What: Replaced
binary.Readwith manual parsing for eBPF events inebpftracer.🎯 Why:
binary.Readuses reflection and allocates memory, which is a significant bottleneck in the hot path of event processing. Additionally, L7 events define large fixed-size arrays (4KB each for request/response) in the struct, causing large unnecessary copies even for small payloads.📊 Impact:
l7Eventstruct allocation.🔬 Measurement:
