Is your machine swapping to disk? Look at top data. I like the curses
util htop -- look on freshmeat. If so, buy more ram, a quieter disk,
or a soundproof case ;)
Start gathering more data for your system. I recommend enabling sar
data collection at 30 minute intervals (even hourly may be good
enough). sysstat includes a cool tk sar data visualizer called isag -
look for it and check it out.
Gather data with iostat. Example: "iostat -d 1 20" show per-device
read/write stats every 1 second for 20 seconds.
