Test Results

Test Environment:
  • CPU: Apple M1 Pro (arm64)
  • Memory: 16GB
  • Backends: 3 Python HTTP servers
  • Duration: 30 seconds per test
  • Tool: wrk (4 threads, 100 connections)

​
Note on Results

The Python backends were the bottleneck - they can’t handle high concurrency. For production benchmarks, use fast backends (Go, Rust, Node.js). Despite this, UltraBalancer performed within 15% of NGINX - competitive for a young Rust project!
