Slow preloading

Hello,

I have 15k items in total and 5k in-stock items in my store, I use YOAST SEO for the site map. When I press Preload button I get an error message: “an unexpected response was received” then I press the button again it was showing the same message. But it seems that preloading is working, just is very slow.

I understand that you may limit the ressurses it uses. As I have a Dedicated server, and I see that the CPU is working on 2%-5% I want to ask you how can I increase the limits.

I can change the code if you will give me the information.

Or there is a setting that I did not find yet?

This plugin is amazing and I am really proud of what you and your team have achieved.
