This can be noticeable if you leave a session logged in all night and your system runs updatedb at 3am, causing all your idle processes to be swapped out. You then find the system really slow for a minute or two in the morning as it drags images back in. To be fair, I've noticed this a lot less with recent versions of Fedora. Maybe I just have more RAM :-) poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
