Cache Benchmarks

Recorded on 2026-08-24 with Go 1.26.0 on linux/amd64 and an Intel
i7-13700H. Results vary by CPU, scheduler, and dependency version.

Comparison

• InMemoryCache reads in about 100 ns without allocating and writes in about 622 ns.
  
• Ristretto reads in about 136 ns and writes in about 3.9 microseconds.
  
• Redis through miniredis reads in about 36.5 microseconds and writes in about 48.9 microseconds.
  

Warp Bench Tool

The warp-bench command measures the complete in-memory Warp path.

Build and Run

go build -o warp-bench ./cmd/warp-bench/main.go
./warp-bench -c 50 -n 500000 -d 256

Results (Core / In-Memory Standalone)

Environment: the same machine and toolchain recorded above.

These numbers measure the in-memory standalone path without network I/O.
