My WooCommerce backend is basically unusable. Product pages take 45+ seconds to load in wp-admin. Front-end is "fine" (3-4 seconds). Host says I'm on "unlimited" shared plan with "no issues detected." I've disabled plugins, switched to default theme, still garbage. Origin server response time is 8000ms+ on simple queries. Anyone seen this pattern? I'm about to edge this whole site onto Vultr's CDN but worried the origin is the real problem. Cache hit ratio won't save admin panels.
