hmm, then I'm wondering why my machines do swap quite a bit. It's a
almost naked linux, the only processes really doing some work are
varnishd and varnishlog.
I have 32 GB of RAM, 30 GB of swap, and 517 GB of cache file. according
to "top", varnishd has a resident size of 25 GB, and almost 1,5 GB of
swap is in use. kswapd often shows up in "top".

it's not worrying me, performance is brilliant, I'm just curious :-)
