 * Hello,
 * I’ve noticed that after activating the **Converter for Media – Optimize images
   | Convert WebP & AVIF** plugin on all of my WordPress sites (about 10 sites, 
   each with around 300 visitors per day), the server CPU load progressively increases
   and becomes very high, reaching around 1500%.
 * When I deactivate the plugin on all sites, the CPU load drops drastically to 
   about 500%.
 * The load increase seems to be progressive with every request, suggesting some
   kind of resource leak or inefficient processing in the plugin.
 * Could you please investigate this issue? It’s causing significant performance
   degradation on multiple sites.
 * Thank you!

 * Hi [@marinow1991](https://wordpress.org/support/users/marinow1991/),
 * Thank you for your message.
 * Tell me please, what did you do after activating the plugin? Did you change any
   plugin settings or run the bulk image optimization process? This is a very important.
 * Best,
    Mateusz

 * Hi Mateusz,
 * Thank you for your reply.
 * I haven’t changed absolutely any settings in the plugin. I just started disabling
   the plugin gradually on the sites, keeping each disabled for about 10 minutes,
   and I noticed the CPU load started dropping immediately. Then, I began re-enabling
   the plugin step-by-step, but the load did not rise again. It’s like some process
   gets stuck or blocked.
 * If it matters, I am using the PRO version of the plugin, and all images are in
   AVIF format.
 * In the screenshot below, you can see a green line on the graph which marks the
   start of disabling the plugins.
 * By the way, now that I think about it, I had the same issue about a month ago,
   but back then I had fewer sites and the load wasn’t so heavy.
 * I hope this helps clarify the situation. Please let me know if you need any more
   info.
 * Best regards.

 * [@marinow1991](https://wordpress.org/support/users/marinow1991/) Your issue concerns
   the PRO version of the plugin, so I can’t help you there. I can only help with
   the free version on this forum. Those are the forum rules. I hope you understand.
 * Please contact me directly via email: `hello(at)mattplugins.com`. I’ll do my 
   best to help.
