Performance issues #1614
ConEmu build: 180528 x64 (stable)
When computer is on for a long time, eventually the FPS in conemu drops to uncomfortable levels (~3-6, normally, it's 45-50). It reproduces fairly consistently on my computer (I have it turned on all the time), I'm not sure if it's the uptime that causes it, but it definitely occurs after a few days after last reboot and rebooting the computer mitigates the issue for several days.
I don't have statistics on how many days it took in the past before performance dropped, but in the latest issue it took 6.5 days.
Closing and reopening ConEmu does not help. Signing out and signing back in does not help. Rebooting the machine helps. No process was consuming any considerable amount of CPU. Not sure what was ConEmu's CPU usage, didn't check and I already rebooted, so need to wait till it reproduces again.
Steps to reproduce
Cursor jumping, skipping a bunch of files each time. Overall sluggish reaction to key presses.
Smooth scrolling, negligible delay before console reacts to a key press.
Ran ConEmu in a VS profiler for a few seconds while holding the key.
I guess I need a debug symbols to see Conemu function names, but it seems it spends most of the time inside the
And I'm interested in exact function names in ConEmu64.exe.
I've also noticed that total memory usage in the system was quite high after 4 days (33 out of 32 GB as reported by process explorer), after killing all high memory using processes (usage dropped to ~14 GB) I did see some perf improvement (FPS/RPS went up from 10.6 to ~11.5), but I'm not sure how significant the improvement is. I just rebooted, and after reboot memory usage is at ~7.5 GB and ConEmu FPS is ~45 and RPS is 70+.
