I'll have to observe a while. It does seem to be having fewer slow-down moments, but since the behavior was not happening consistently all the time, I can't be sure. Keep this thread open another couple of days and I'll have a better idea.
Can I know what it was that has changed? Did one of the things I ran actually DO something?
Also, I'd like to get help understanding what all is running. I have programs running that I don't know anything about, but am not sure if they are important or not. Would cleaning that up help? Is there anything else I can do to help performance?
