Although system specs in this test were irrelevant, I do have a P4 3.2GHz machine with 2GB PC3200 RAM, I'll try and do the same test on that machine later. As I said to Riamus2 earlier, you may not notice something like that, it was barely noticeable to me on the machine I noticed it on, but I notice things like that because it drives me crazy. I noticed a little difference in response after it had been running for a couple days so after reading this thread I wanted to test it against 6.3 on an older/slower machine and there it was very noticeable. I notice things like this like you would notice a fly on your nose, which is also why I reinstall the OS every few months.
