We Rewrote VictoriaMetrics in Rust. It Now Beats the Original on Every Benchmark Metric

Short summary

EsMetrics, a new Apache 2.0 Rust rewrite of VictoriaMetrics single-node, outperforms the original Go implementation across all TSBS benchmarks—43-66% faster ingestion throughput and 11-82% lower query latency. The project prioritizes byte-identical correctness against the Go server, using a replay harness to catch semantic bugs. Major optimizations include parallel unpacking with per-worker scratch buffers, decoded-block caching, zero-copy ingestion, and platform-specific fixes like MiMalloc on Windows to avoid global heap lock serialization.

• •EsMetrics (Rust) beats Go VictoriaMetrics on all benchmarks: 43-66% faster ingestion, 11-82% lower latency
• •Byte-identical correctness enforced through replay harness, catching real semantic bugs in equivalence testing
• •Key optimizations: parallel unpacking, block caching, zero-copy ingestion, Windows allocator tuning (MiMalloc)
