Conversation
- Added Rust-native event loop (run_until_stopped) - REVERTED as it was 3x slower due to FFI overhead when calling Python callbacks from Rust - Fixed buffer leak on FD reuse (release existing buffer before overwrite) - Removed buffer quarantine for immediate reclamation - Updated PyO3 default buffer_count to 4096 - Added pipes.py for StreamReader/StreamWriter API - Added comprehensive benchmarks vs asyncio and uvloop Results: - uringcore beats asyncio: 18/21 benchmarks - uringcore beats uvloop: 15/21 benchmarks - Known limitation: sock_pair benchmark skips due to RLIMIT_MEMLOCK buffer pool size constraint
- Increased buffer_count from 1024 to 4096 for high-throughput sock_pair benchmark - Reduced buffer_size from 32KB to 8KB to fit within RLIMIT_MEMLOCK (32MB total) - Updated benchmark_suite.py defaults to match sock_pair benchmark now passes: 22.84µs/op (beats uvloop 28.88µs/op)
