Tested with unix socket looper server and client progrrams
and saw no I/O percentage on behalf of either program. At the
time I filed this bug I was having a lot of problems with sluggish
performance and VM stress (as reported by 'sar -B' and atop
among other diagnostic tools). Ultimately I ditched gnome(-shell)
altogether and installed xfce4, and saw a great improvement in
response time, as well as an overall reduction of swap and paging I/O.
I think we can chalk this phenomenon up to blkio and/or swapin
delay on behalf of gnome-shell and pat iotop on the back as having
helped diagnose the problem.
Thanks for your work on iotop. OK to close.
