My primary suggestion is to check swap usage (can also be done with top, or free). I know we're not running MS Windows here, but I have yet to find a perfectly behaved browser that doesn't eventually leak memory, and if you're like me, you have a browser running for Quite Some Time between restarts, and you may end up using swap even with very little actually currently "happening" on the system. I usually don't need a reboot to reclaim the swap, but I'll restart the browser, and if I want to verify that the swap usage is gone, I'll swapoff -a; swapon -a (as root) to verify that all of that 'used' swap isn't really being used anymore.
This last step is not necessary, since the stuff that is swapped out is either unlikely to swap back in and is fine sitting on disk, or does swap in once and then isn't swapped back out (until the next iteration of the vicious cycle), I just like seeing Swap at 0 because it satisfies some compulsion I have for closing things :) That's what tends to cure my "occasional slowdowns" that aren't network-filesystem-related, YMMV On Thu, May 5, 2016 at 7:54 AM, Dick Steffens <[email protected]> wrote: > My desktop machine used to respond quickly to the opening of a program, > or the return from screen saver.
