LiteSpeed Cache for WordPress — What Actually Helps
Practical LiteSpeed Cache settings for WordPress on HostRadar — page cache, object cache, and what to avoid on WooCommerce.
By HostRadar Team
Cache is not a substitute for bad queries
LiteSpeed Cache can turn a 2-second page into a sub-second experience — if the HTML is cacheable. Logged-in carts, membership dashboards, and personalized blocks need careful exclusions.
On HostRadar WordPress plans
Our WordPress Pro hosting stack is built around LiteSpeed so server-level cache and the plugin speak the same language. Pair that with solid storage from NVMe hosting when the database is the bottleneck.
Sensible defaults
- Enable public page cache for anonymous visitors
- Purge on post update
- Exclude cart, checkout, and my-account on WooCommerce
- Consider Redis/object cache only when you understand eviction
Measure before and after
Use TTFB and Largest Contentful Paint — not only a homepage screenshot. If cache helps anonymous traffic but checkout still lags, look at NVMe IOPS and PHP workers next.
