FacetWP itself is exceedingly fast. It normally takes a fraction of a second to load results. However, every WordPress request (including AJAX) is only as fast as the slowest plugin.

AJAX requests are ignored by most caching plugins, so the load time you’re seeing with FacetWP is your server’s true speed.

If FacetWP takes a while to load, there’s likely a larger underlying issue. Make sure to disable any unnecessary plugins, and ensure that your server has sufficient resources.

We have a free Caching add-on that may help on high-traffic sites. Please read the installation instructions carefully, since it requires a few extra steps.
