💡 What: Replaced reflection-based binary.Read with manual binary.LittleEndian parsing in the hot eBPF event loop.
🎯 Why: binary.Read is slow and generates significant allocations, causing CPU overhead in high-throughput scenarios (like L7 tracing).
📊 Impact:

  • L7Event parsing: ~380x speedup (104,945 ns/op -> ~270 ns/op)
  • TcpEvent parsing: ~7x speedup (1,377 ns/op -> ~180 ns/op)
  • Allocations reduced from 9KB/op to 0-384B/op.
    🔬 Measurement: Verified with ebpftracer/parsing_test.go benchmarks and correctness tests.

PR created automatically by Jules for task 677377576200725842 started by @blue4209211

Replaced `binary.Read` with manual parsing in `ebpftracer` to eliminate reflection overhead and reduce allocations.
Includes correctness tests and benchmarks.
