How to improve Outlook 2007 response

I had been seeing slow responses in my Outlook for a while and when I googled I came across this post which talked about disabling add-ins - http://www.notesfromatooluser.com/2007/04/is_outlook_2007.html
I tried it and does look like its improved. I had actually installed Adobe Acrobat and that had added an Outlook addin. This was recently and I think that was the main culprit!
