Go vs Rust for Backend in 2026 — Real Benchmarks (Throughput, P99 Latency, Memory, Cost)
I built both Ajaya (Rust web framework, 307K req/sec) and Rudra (Go web framework, 206K+ req/sec) on this channel. Now I'm putting them head to head with the same API, real benchmarks, and infrastructure cost math.
TechEmpower Round 23 data. P99 latency under load. Memory at 200 and 2000 concurrent connections. Binary size, startup time, compile time. And the clearest decision framework I can give you for 2026.

00:00 — Hook: I built frameworks in both — here's the honest comparison
01:30 — Partner: CodeCrafters
03:46 — Architecture: GC vs ownership (why P99 matters more than avg)
06:13 — Quick like + subscribe
06:25 — Building the same API: Axum (Rust) + net/http (Go)
07:18 — Benchmark results: throughput, P99 latency, extreme load
08:59 — Memory: 42MB (Rust) vs 115MB (Go) — infrastructure cost math
10:19 — Compile time: 2s (Go) vs 60-90s (Rust) — real dev velocity impact

📊 BENCHMARK RESULTS (same API, same hardware)
━━━━━━━━━━━━━━━━━━━━━━━━━━━
Throughput (200 connections):
• Rust (Axum): ~280,000 req/sec
• Go (net/http): ~190,000 req/sec
P99 Latency (200 connections):
• Rust: 1.2ms
• Go: 2.8ms
P99 Latency (2000 connections — traffic spike):
• Rust: ~4ms (steady)
• Go: ~18ms with occasional 30ms+ GC spikes
Memory at steady state:
• Rust: ~42MB
• Go: ~115MB
Compile time (clean release build):
• Go: 2 seconds
• Rust: 60–90 seconds
Binary size:
• Rust: ~3.2MB
• Go: ~6.8MB
