⚡ Bolt: Optimize eBPF event parsing#182
Conversation
Replaces `binary.Read` with manual parsing using `binary.LittleEndian` for eBPF event deserialization. This avoids reflection overhead and unnecessary allocations/copies, especially for large `l7Event` structs. Impact: - Reduces allocations per event. - Reduces CPU usage in the hot path of event processing. - Avoids copying full 4KB buffers for `l7Event` payload/response when actual data is smaller.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

⚡ Bolt: Optimize eBPF event parsing
💡 What: Replaced
binary.Readwith manual binary parsing forl7Event,fileEvent,procEvent, andtcpEvent.🎯 Why:
binary.Readuses reflection and allocates full structs, which is a bottleneck in high-frequency eBPF event processing loops.l7Eventwas particularly expensive as it involved copying 8KB of data for every event regardless of payload size.📊 Impact: Significant reduction in CPU usage and allocations for event processing.
l7Eventprocessing is now O(payload_size) instead of O(max_buffer_size).🔬 Measurement: Verify with
go test -v ./ebpftracer/...and benchmarks (if available).PR created automatically by Jules for task 231994658884104626 started by @blue4209211
