Hi!
Sorry for the late answer, I investigated the issue on my server, but I couldn’t get any good results.
Can you please add more details about the issue above?
Are you doing a search when the tabs are opened, or the performance goes up only by opening the tabs?
There is one possible thing, that can cause this:
Precaching. If the precaching in the caching settings is activated, it parses through the posts and saves the image thumbnails, it’s a processor-heavy operation on some servers. (it depends on the amount of posts and the complexity of the post content)
Please try to turn off the precaching and let me know how it affects the cpu load, it may help.
If not, then I will figure out another solution as well.
Best,Ernest Marcinko
