Swift Performance Pro adds CDN integration, image optimization, and a critical CSS pipeline on top of the Lite cache layer. Cache files live under wp-content/cache/swift-performance/, CDN configuration sits in swift_performance_pro_cdn options, image jobs are tracked through the plugin's media queue, and critical CSS rules are stored per template. The plugin's dashboard shows totals per area on separate tabs.

SleekView Charts reads the same directory and option rows and renders chart cards on one dashboard. A Number card counts total cached URLs. A Donut splits image optimization across done, queued, failed. A Bar shows critical CSS coverage by template. An Area chart trends CDN purges per day so a release schedule becomes legible without opening the CDN tab.

Swift Performance Pro continues to handle cache writes, CDN purges, image jobs, and critical CSS generation exactly as before. SleekView Charts is read-only against the same data, with row actions that call the plugin's own functions when an inline action is helpful. Saved chart views are scoped per role so an agency engineer can audit cache health without access to API keys or license settings.

Swift Performance Pro adds the right things on top of the Lite cache layer: CDN integration, image optimization, critical CSS generation. The trouble is that each of those features gets its own tab and its own counter set, so a release that affects all four areas needs four tab switches to evaluate. SleekView Charts reads the same cache directory, CDN options, image queue, and critical CSS rules, and renders them as chart cards on a single dashboard.

Engineers see the full picture without context-switching. Ops sees the side of the picture they own. Owners see the high-level KPI without admin access.

The plugin keeps doing the optimization work it does well; SleekView Charts gives the team a shared screen to read it.
