Performance Architecture
Engineered from the ground up so multilingual never means slow.
🚀
3-Layer Cache
In-memory, persistent (Redis/Memcached), and database caching layers. Most page loads are served from the fastest layer with zero database queries.
📦
Batch Preloading
When WordPress loads a list of posts, PerfLocale loads all translation data in a single efficient request instead of one query per post.
🔎
Smart Query Optimization
Language filtering is added directly into WordPress database queries, so one query does the work of many. No extra overhead for your visitors.
⏱
Less Than 5ms Overhead
On-demand loading, instant string lookup, and all optimizations combined deliver less than 5ms of overhead per page load on a typical site. See the measured numbers →
