What object caching actually fixes
Object caches store expensive PHP objects (menus, option rows, heavy queries) across requests. They shine when your theme or WooCommerce store repeats identical lookups thousands of times per day.
Redis vs Memcached on HostStack stacks
Both can back persistent caches — Redis adds richer data structures if your stack exposes it. Availability depends on plan and server profile; ask support before you assume sockets exist.
Measure before bragging
Compare Core Web Vitals field data (CrUX) or lab URLs — not admin-ajax chatter alone. Pair caching with sensible plugins and image hygiene from our slow-site checklist.
