Hello,
for a while now, on some Joomla sites where I have K2, I've been noticing some lag in the backend.
More specifically, sometimes (not all the time), when I open K2 to see the list of my articles or add a new article, for about 30 seconds it doesn't let me do anything (lag) and then it hangs and works normally!

The problem came on suddenly without any change to the hosting package or any increase in traffic.
Website runs on PHP version 7.4 (FPM mode)
What else do you want me to send you?

I forgot to mention that,
when I open it from a mobile device, the backend works normally without any lag.
The lag only occurs from a desktop or laptop!
