All of this is for Unity 2020.2.0f1 So I was trying to dig into why making a fairly large UI Toolkit UI took 4 seconds, which made it kinda useless. I ran it through the editor deep profiler. Trying to figure out what was going on was made painful due to the profiler often taking 20+ seconds to select... anything. A frame, a row in the hierarchy, etc. So I figured that I should try to send a bug report for that - or at least check if it was due to me running low on memory (I only have 16 gigs, after all!), so I decided to save the profiler data to a file so I could open it in a different project that doesn't require as much ram to be open. Then I could check if the slowness was consistent. aaaand: That might be a problem. Two questions: - why can't I save profiler frames that are over 2GB? - what on earth is happening to cause the frame size to be larger than 2GB? That seems excessive!
