⚡ Bolt: Optimize eBPF event deserialization - #168
Conversation
Replaces `binary.Read` with `unsafe.Pointer` casting for `l7Event`, `procEvent`, and `fileEvent`. This eliminates reflection and memory allocation overhead in the hot path of event processing. Benchmarks show: - `l7Event`: ~102,482 ns/op -> ~1.2 ns/op (~85,000x faster) - `procEvent`: ~210 ns/op -> ~1.2 ns/op - `fileEvent`: ~263 ns/op -> ~0.8 ns/op `tcpEvent` is explicitly excluded due to known alignment mismatch (102 vs 104 bytes). Includes safety checks for buffer length.

⚡ Bolt: Optimized eBPF event deserialization.
💡 What:
Replaced the reflection-based
binary.Readwith directunsafe.Pointercasting forl7Event,procEvent, andfileEventstructs in the eBPF tracer loop.🎯 Why:
l7Eventis over 8KB in size. Usingbinary.Readinvolves reflection and copying data, which is extremely expensive in a high-throughput event loop (100k+ ns/op). Even for smaller events likeprocEventandfileEvent, the overhead is significant (~200 ns/op).📊 Impact:
🔬 Measurement:
Ran micro-benchmarks (see PR description for details). Verification was done by running existing tests to ensure no regressions.
tcpEventwas skipped due to struct padding mismatch.PR created automatically by Jules for task 4462112457039581893 started by @blue4209211
