Fair enough, I'm gonna give 3.0 a few updates to cook and then I will see if it's still super laggy on my end still, it's weird cause the 2.x version runs completely fine but 3.0 lags to the point where even selecting layers makes takes a literal second.
When you compare the performance you are experiencing to the screen recording in the bug I linked to, is it comparable, or worse? If the latter, then it may be useful if you could file a report and attach the performance log as well.
It's not comparable actually, my cpu usage never goes above 8% and out of the 8 gigabytes of memory I gave the program only 2 at most are ever used. My cache is at 0% as well but idk if that's relevant, do you want my pc specs?

Not in particular, though this may depend a lot on your use cases.
There was a post here some time ago about a slightly worse performance, and an issue report had been file based on that subsequently: https://gitlab.gnome.org/GNOME/gimp/-/issues/13076
We haven't had much time to look into that these past few days right before 3.0.0, but eventually someone will be able to do so.
