I think you're somehow missing my point. I intentionally did the tests on a slower machine. Both had no loaded scripts nor dll's. Both had no background images. No other programs running. Both sitting idle on the same four very busy channels with lots of colors (yes mp3 channels), both on the same machine, both using the same mirc.ini (same exact settings). In those conditions, 6.31 was a lot more sluggish after the hour was up than 6.3 was. System specs are irrelevant when the two different versions were measured under the exact same conditions. Granted, you're running a dual core, 64 bit, 3GHz processor with 2GB PC6400 RAM so no, you may not notice it. I barely noticed it on my dual core, 64 bit, 2.20GHz processor with 2GB PC6400 RAM, but I noticed it enough to to make me want to test it on an older, slower machine where it was WAY noticeable.

Have any of you guys tried SeaMonkey? After using this for the past week, Firefox (Bloatware) sucks. I'm really impressed with it. You should try it.
