I don't see any attachments. First, I would upgrade to 5.5 as 5.0 is very old. The upgrade process is painless.
Second, make sure your Innodb buffer pool is allocating as much ram as possible. I'd even go as far as adding another 8gb of ram to the server. The buffer pool setting is going to give you the best performance increase. Also, what kind of hard disks do you have the data files on? Raid? No raid?
