I'd like to know what the swapper process actually does (I know, I know, it
swaps :-).
The reason I ask is that we are running a performance and capacity planning
tool called Best1 on our servers and it shows that the swapper is almost
always the top process for various statistics including accumulated CPU,
I/O, etc. over a period of time. Other processes are also long running and
we were surprised to see the swapper at the top.
This would be Ok on a system which is swapping heavily but one of our systems
is acting only as an NFS server and does not swap, yet the swapper
process still clocks up a lot of usage. Does the swapper handle anything
else such as cleaning out the UBC?
