When building infrastructure for high-traffic WordPress sites, every millisecond matters. We chose Rust over Go for Smooth Search, and here’s why.
Zero-Cost Abstractions
Rust’s compiler optimizes aggressively. There’s no garbage collector pausing your search mid-query. Memory is managed at compile time through ownership, not runtime through GC pauses.
// This costs nothing at runtime
let results: Vec<_> = products
.iter()
.filter(|p| p.matches(&query))
.take(10)
.collect();
Real-World Impact
In our benchmarks against a Go implementation:
- 35% faster index building
- Zero GC pauses vs Go’s 10-50ms stops
- 40% smaller memory footprint
- Predictable latency - no tail latency spikes
Go is great. But for search infrastructure where every millisecond compounds across thousands of requests, Rust’s zero-cost abstractions win.
Performance isn’t just a feature. It’s the foundation everything else builds on.
