Why is openserver dumb on page load?

Question

MySQL

Hello, the breakdown happened suddenly - I didn’t change anything in the settings, I’ve been working on the open server for the second year already, I did a bunch of sites, everything was ok, and today suddenly it started to look stupid when loading / updating pages, 9.5-10 seconds - the time is always the same (checked on different sites) looks like this in the console:

For about 9.5 seconds nothing happens after pressing F5 - the site works as it worked (i.e. the video, for example, plays the same 9.5 seconds after the update), then the site loads in half a second. It is clear that it is impossible to work like that, I checked all the settings - they are as they were, there is also enough space on the hard drive, there are no problems with resources at all, sites on Wordpress, I tried different ones - the result is the same delay of about 9.5 seconds and then all the rules are loaded. Then I tried the same sites on real hosting - they work as they should without this lag, so problems with the sites are excluded.
Pure HTML pages load instantly:

From here there is an assumption that this is somehow connected with databases, I deleted a bunch of old databases that were there from old sites - but this did not help. It is also not clear what was the reason - after all, yesterday everything worked as it should.
UPD I noticed that all these 9 seconds the status is pending - like pending, what is he waiting for 9 seconds?

Answer 1

In general, it was not in the open server, but in the sites themselves, they were infected with wp_vcd

Answer 2

Disable Wordpress auto-updates and stop being stupid. It is convenient to do this with the Clearfy plugin.
