Swift Performance Lite caches page output to disk under wp-content/cache/swift-performance/ per host and per URL, and stores configuration plus optimization flags in swift_performance_* options. The plugin reports aggregate stats inside its dashboard tab: total cached pages, cache size, last warmup time. There is no per-URL list of cache state, no hit ratio over time, and no breakdown of which asset optimizations are active across the site.

SleekView Charts indexes the cache directory and the swift_performance options, then turns that data into chart cards. A Number card sums total cached URLs. A Donut splits cache state across cached, warming, stale, and missing. A Bar groups cache size by post type so heavy templates surface. An Area chart trends daily cache refreshes so you can see how preload runs behave after a deploy.

Swift Performance Lite keeps caching and serving pages exactly as before. SleekView Charts is a read-only dashboard against the same files and options, so the cache pipeline and the existing rewrite rules continue without change. Saved chart views are scoped per role, useful for letting a developer triage cache health without access to license keys or critical CSS settings.

Swift Performance Lite is fast at writing cache and aggressive about optimization, but the reading side is still a set of aggregate counters on a single dashboard tab. Cache size grows quietly. Preload schedules drift.

A deploy can empty the cache without any visible signal that the refresh is taking longer than usual. SleekView Charts treats the cache directory index and the option rows as the structured data they already are. Cards expose state mix, file size per post type, refresh trends, and hit counts in one shared dashboard, scoped per role, and embeddable on the frontend for stakeholders without admin access.

The plugin keeps doing the heavy lifting; SleekView Charts adds a reading layer the team can actually share.
