From dc6092c244a97e71b0e3a7555f9602171a380310 Mon Sep 17 00:00:00 2001 From: floor-licker Date: Sat, 6 Dec 2025 17:47:35 -0500 Subject: [PATCH] feat: integrate infrastructure modules and achieve 8.9% performance improvement Integrated DNS caching, connection manager, and buffer pool modules into ClobClient structure to enable production use. Added start_keepalive() and stop_keepalive() methods for maintaining warm connections through background keep-alive pings. Implemented DNS cache pre-warming on client initialization and buffer pool with 512KB buffers for reducing allocation overhead. Cleaned up temporary test and analysis files from optimization exploration. Benchmark results with keep-alive enabled show 368.6ms mean latency compared to polymarket-rs-client's 404.5ms, representing 8.9% improvement and 35.9ms faster performance while maintaining production-safe approaches --- README.md | 10 +- examples/advanced_network_optimizations.rs | 232 ----------------- examples/benchmark_with_keepalive.rs | 81 ++++++ examples/compare_payload_sizes.rs | 85 ------ examples/memory_benchmark.rs | 284 --------------------- examples/network_optimization_test.rs | 152 ----------- examples/network_timing_test.rs | 137 ---------- examples/profile_latency.rs | 94 ------- examples/test_burst_requests.rs | 140 ---------- examples/test_connection_reuse.rs | 70 ----- examples/test_prewarmed.rs | 119 --------- examples/test_simd_json.rs | 71 ------ src/client.rs | 123 ++++++++- 13 files changed, 206 insertions(+), 1392 deletions(-) delete mode 100644 examples/advanced_network_optimizations.rs create mode 100644 examples/benchmark_with_keepalive.rs delete mode 100644 examples/compare_payload_sizes.rs delete mode 100644 examples/memory_benchmark.rs delete mode 100644 examples/network_optimization_test.rs delete mode 100644 examples/network_timing_test.rs delete mode 100644 examples/profile_latency.rs delete mode 100644 examples/test_burst_requests.rs delete mode 100644 examples/test_connection_reuse.rs delete mode 100644 examples/test_prewarmed.rs delete mode 100644 examples/test_simd_json.rs diff --git a/README.md b/README.md index 508d63a..eb8eb02 100644 --- a/README.md +++ b/README.md @@ -50,12 +50,14 @@ End-to-end performance with Polymarket's API, including network latency, JSON pa | Operation | polyfill-rs | polymarket-rs-client | Official Python Client | |-----------|-------------|----------------------|------------------------| -| **Fetch Markets** | **382.6 ms ± 75.1 ms** | 404.5 ms ± 22.9 ms | 1.366 s ± 0.048 s | +| **Fetch Markets** | **368.6 ms ± 67.1 ms** | 404.5 ms ± 22.9 ms | 1.366 s ± 0.048 s | **Performance vs Competition:** -- **5.4% faster** than polymarket-rs-client (Rust) - 21.9ms improvement -- **3.6x faster** than Official Python Client +- **8.9% faster** than polymarket-rs-client - 35.9ms improvement +- **3.7x faster** than Official Python Client + +**Note:** Best performance achieved with connection keep-alive enabled (`client.start_keepalive(Duration::from_secs(30)).await`). **Computational Performance (pure CPU, no I/O)** @@ -67,7 +69,7 @@ End-to-end performance with Polymarket's API, including network latency, JSON pa **Key Performance Optimizations:** -polyfill-rs achieves 5.4% better performance than polymarket-rs-client through several targeted optimizations.
