1. I noted I had a partition for temp files, which I used for like browser cache files, etc, and a partition for swap files. The idea being these are files which get cause a lot of disk activity, and having them in a well-defined disk area with no other content there makes that activity faster. Ie ~= scratch files. 2. (How can you have a 2.6 GB "partition" you seem not to have known about? Cf for swap partition--ie virtual memory--I myself followed one usual unix rule and made it approx same size as my RAM.)
