Bug#471152: gnome-system-monitor: Confirmation of problems: CPU history takes a LOT of user time on cpu

[Todd A. Jacobs]

Package: gnome-system-monitor
Version: 2.22.1-1
Followup-For: Bug #471152


I'm running a dual-processor quad-core, and am experiencing high CPU
utilization on one or two cores every time I open the resources tab on
System Monitor. Setting the default update interval higher (e.g. around
4 seconds) for graphing reduces the load on the active cores to around
35% user, but X remains VERY sluggish and unresponsive until the system
monitor is closed. This would seem to indicate a polling problem, so
I've included a partial strace (more if you need it):

poll([{fd=8, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI, revents=POLLIN}, {fd=13, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN|POLLPRI, revents=POLLIN}], 4, -1) = 2
read(12, "GIOP\1\2\1\1$\0\0\0", 12)     = 12
read(12, "\330;\306\353\0\0\0\0\1\0\0\0\1\0\0\0\f\0\0\0\1\1\1\1\1"..., 36) = 36
read(14, "GIOP\1\2\1\0\372\1\0\0", 12)  = 12
read(14, "h\30\3\376\0\0\0\0\0\0\0\0\34\0\0\0\0\0\0\0\213l\2408\250"..., 506) = 506
writev(12, [{"GIOP\1\2\1\0l\0\0\0", 12}, {"x<\306\353\3\0\0\0\0\0\0\0\34\0\0\0\0\0\0\0:\16d\260\360"..., 108}], 2) = 120
poll([{fd=8, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI, revents=POLLIN}, {fd=13, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN|POLLPRI, revents=POLLIN}], 4, -1) = 2
read(12, "GIOP\1\2\1\1$\0\0\0", 12)     = 12
read(12, "x<\306\353\0\0\0\0\1\0\0\0\1\0\0\0\f\0\0\0\1\1\1\1\1\0"..., 36) = 36
read(14, "GIOP\1\2\1\0\252\1\0\0", 12)  = 12
read(14, "h\30\3\376\0\0\0\0\0\0\0\0\34\0\0\0\0\0\0\0\213l\2408\250"..., 426) = 426
writev(12, [{"GIOP\1\2\1\0p\0\0\0", 12}, {"x<\306\353\3\0\0\0\0\0\0\0\34\0\0\0\0\0\0\0:\16d\260\360"..., 112}], 2) = 124
