I thought that it may be from some software I recently installed that may be hogging some memory but after un-installing all of it, I'm still getting lag. I don't know what's causing it for all was fine up until today.

--you could try renice every so often
and see if you still get the slowed response to your particular set of activities (application that are running or backgrounded!)
If you can, you could also try nice to manage the priorty of the process/application you need to have such a priority
For interest, you could have a look at the kernel scheduler, but Linux desktops today use a pre-emptive scheduler which improves desktop OS responses (foreground usually)
A T61 is an older notebook, I would probably ask first: how much RAM is installed

--I see the max RAM is 4GB, not that much for a 64bit OS version, more RAM really helps Linux a lot in terms of performance
--you might get better performance using a 32bit OS install with PAE extension, if you want to partition the RAM (and assuming it is at MAX 4GB) to get the most space for the user applications..
Also check the SWAP space being used, or use top or htop to check: if you have plenty of RAM free, you won't have any swap space being used..

--maybe some more data can be shown, why it may be considered better?
