My Ubuntu has been running pretty slow, but I don't know why. I have the latest updates and all. I installed Ubuntu i368 on a AMD processor does that effect the speed? Thank you.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

You need to add more information about your hardware, free disk space, memory and exactly when does it get laggy? – Zuul Jul 5 '13 at 0:02

Very little information to go on here, but I'm going to take a shot at it anyway. Normally when Ubuntu gets laggy for no obvious reason it has to do with gvfs-metadata. This is particularly true if you've been moving files around a bit. It's a pretty easy fix. All you have to do is close Nautilus or whatever file browser you are running, open an terminal and type the following:

pkill gvfsd-metadata

then hit ENTER and when you get the prompt back, type:

rm -rf ~/.local/share/gvfs-metadata

The first command stops the gvfsd process, and the second command erases gvfs-metadata file which often becomes corrupt or just too big. Don't worry, though, a fresh new gvfs-metadata file is created as soon as the gvfsd process starts back up. At the very least this does no harm and gives you a bit more speed / CPU usage. The worst case scenario is that you see a bit of improvement. The best case is that this fixes your problem.
