Server Load Spike

Hello,

I am experiencing a significant CPU/load spike on my WordPress site when the FS Poster plugin automatically shares a newly published post.

After investigation, I noticed the following:

• When I publish a post with FS Poster auto-share enabled, the server load spikes significantly.
• When I publish a post without FS Poster auto-share, the load remains normal.
• I already disabled “All Pages” Auto Purge in LiteSpeed Cache, but the spike still occurs.
• It seems the spike happens when FS Poster triggers its sharing process after publishing.

My suspicion is that LiteSpeed Cache optimization processes (such as CSS/JS optimization, UCSS, Critical CSS generation, or other background tasks) or purging might be triggered when the FS Poster process runs through WordPress hooks or WP-Cron.

Could you please advise:

1. Whether LiteSpeed Cache runs optimization tasks when plugins like FS Poster trigger publish/update hooks.
2. If there is a recommended way to exclude a specific plugin (like FS Poster) from LiteSpeed optimization or background processing.
3. Whether excluding wp-cron.php or the plugin directory from optimization is the correct approach.

I would appreciate any recommendations to prevent these load spikes while keeping LiteSpeed Cache optimization enabled.

Thank you for your assistance.
