Vicki, I know you have been around here a long time, but I also think that you were not on the board for awhile. I mention that because I wonder if you did not hear about the painful period of time late last year, soon after V6 was released. The bottom line: according to Jon B, about 15% of AC users experienced severe slowing issues...exactly like what you describe...after upgrading to V6. Many were using the same version that you are on. After a difficult period, AC released a rapid release beta which resolved the problem. Steven mentioned it above. Please, before you buy any hardware or take any other major steps, I would suggest that you simply upgrade to V6.12 and see if this solves your slowness issues. If you talk to the Guardian Angels, I would think they would suggest the same.
