all kosher here, I have my FreeBSD workstation and will put some more RAM into it. Just found it out on a penguin..
Honestly, I would never think that adding RAM to a comp with still unused space left could speed it up. Was just a coincident to find it out. But it clearly explains what I noticed--especially Firefox (lots of cache files) and the email client (switching folders with many lil files in there) had shown some difference.
Will give the computer store a visit tomorrow..
