Performance has suddenly gone to hell on a x86_64 machine running debian testing. I noticed in htop that nothing was ever showing in swap, so I checked with 'swapon -s', expecting to find that swap was off for some reason, but instead got this:
Filename Type Size Used Priority
/dev/sda5 partition 4805628 0 -1
So the correct partition is allocated as swap as per /etc/fstab, but that "Used" figure of zero is bugging me. The machine has 2GB RAM, which is usually 90%+ allocated according to htop.
Anyone recognize this?
