Re: [LUG] Swap not swap

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?

My under-used VMWare server instance matches your results -> 0 Used.

My over-used main server with 2GB RAM has a non-zero "Used" value which matches up with top results. - I really should add more RAM to it...

Both are latest Ubuntu LTS servers.
