Support » Plugin: Swift Performance Lite » Spiking CPU Usage

  • To Whom This May Concern,

    After yesterday’s update over night my CPU usage spiked and ran me into warnings with my SiteGround webhost. They said my heartbeat was going crazy and that I needed to stop it. I have Heartbeat deactivated in Swift Performance but something wasn’t working. I ended up restoring my site before the update and the CPU usage is going back to normal. Please let me know what I should do.

    Thank you for your time and help.

    While the plugin is generating the cache the CPU usage can be higher than usual. If CPU usage is constantly higher you may need check the configurations. It is recommended to enable Settings > Optimization > General > Optimize Prebuild Only.

    Generating Critical CSS is the most CPU intensive process. If your site is running on shared hosting you may consider to disable Critical CSS feature, or upgrade to pro version, which provides Compute API (it will generate the critical CSS in cloud).
