Slow response time

jerryDaBaaws · 2020-09-05 14:11:58

Please help, lately startup time of apps have been abnormaly high
If I am launching an app fresh ( no other instance of it is running ) there is always a startup delay of 3-4 seconds.
But if an instance is already running or closed very recently , another one opens pretty fast

Rofi in particular, if you open it after a long time ( more than 5-6 minute) took atleast 5 second to run, but then succesive launch are sudden and quite responsive.

All the regular apps are having such problems ( nautilus, kitty, firefox etc..)

I tried Ubuntu on a usb stick, and the difference between responsiveness was really huge
Any idea why this is happening ?

High memory and/or IO pressure and/or IO errors.
Maybe you messed around w/ vm.swappiness and ended up w/ thrashing.

My install is fairly new, and I dont recall doing anything with swappiness.
But if that's the case, How should I deal with it ? I dont have much knowledge in that regard

You should first figure whether you've RAM/IO issues.
top, free, iotop and dmesg will tell you about the load and the kernel messages (if there're IO errors)

sysctl -n vm.swappiness

should™ be 60 by default.
