Tips for improving Ajax filter performance

Even with Ajax, filtering can slow down on high-traffic or large-scale sites, unless your backend is optimized.

Use object caching to reduce database load.
Exclude filter pages from full-page caching to prevent conflicts.
Keep filter sets simple for faster rendering.
Choose WordPress-optimized hosting that supports PHP workers and scalable memory.
