I have a Dell 8450 with 16 Gb of RAM used for running biological
computations. Currently I have 3.5 Gb of swap, and sometimes it is almost
completely used up even when only 4 Gb of RAM is used. Worse of all,
sometimes kswapd takes up a lot of CPU time. Here is a recent free output:
total used free shared buffers cached
Mem: 16490952 16486332 4620 0 420 12197416
-/+ buffers/cache: 4288496 12202456
Swap: 3578664 2915448 663216
I am trying to understand what is going on, but I do not know much about
swap usage or how to debug it. I do not even know about the proper
newsgroup/mailing list to ask this question, except the linux-kernel list.
(I am not sure whether I should go that far. :)
Thanks in advance for any ideas,
