Hi,
during playing with new build 145 I discovered strange thing:
C0 (cpu running) (100.0%) 1000 Mhz 100.0%
C1 0.0ms (0.0%) 1333 Mhz 0.0%
1667 Mhz 0.0%
Also kstat indicates that system is running on 1GHz only. No difference
between poll-mode and default.
This combination happen when I run intensive compilations (build of
boost with Sun Studio). And it is very strange even more, typical output
of prstat:
9667 mj162486 66M 62M cpu0 30 0 0:00:06 13% ccfe/1
9671 mj162486 60M 55M run 21 0 0:00:05 11% ccfe/1
but top reports:
9643 mj162486 1 31 0 63M 59M run 0:05 46.59% ccfe
9650 mj162486 1 22 0 48M 44M run 0:02 26.60% ccfe
Basically I see much smaller values of CPU usage in prstat than in top.
And I am pretty sure that in reality the CPU (Intel C2D in Thinkpad T60)
is very busy (also Gnome applet shows full load).
If I break compilation and do some "normal" work like browsing, powertop
shows some changes in frequency to higher values.
Best regards,
Milan
