[Bug 520112] New: xosview consumes cpu "sys" cycles
http://bugzilla.novell.com/show_bug.cgi?id=520112 Summary: xosview consumes cpu "sys" cycles Classification: openSUSE Product: openSUSE 11.2 Version: Factory Platform: Other OS/Version: SLES 11 Status: NEW Severity: Normal Priority: P5 - None Component: X11 Applications AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: steiner-reg@bio.ifi.lmu.de QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; X11; Linux x86_64; en) Opera 9.64 We see this on SLES 11 on i586, x86_64 and ppc64, but also with the latest factory/opensuse 11.2 kernel. When starting xosview and leaving the system idle, one of the CPU bars is jumping from 0% to some value between 5% and 9% about twice a second. On identical SLES 10 systems, all CPU lines stay at 0% all the time when the systems are idle. Checking /proc/stat we see that the "sys" column is increasing by about 1 per second. But this seems to come from xosview itself. If we start gkrellm, the CPU sliders stay at 0 all the time and the "sys" column in /proc/stat doesn't change. The moment we start xosview, the sliders in gkrellm start jumping back and forth, too. It seem the method xosview scans the system did not use any measurable "sys" cpu cycles in kernel 2.6.16 (SLES 10) but now in SLES 11 (2.6.27) or Factory (2.6.30) it does. It is really annoying if xosview flashes about twice a second all the time when you are doing nothing. Is there any chance this could be fixed? I already tried to replace the code reading and generating the cpu stats with the code that gkrellm uses, but this alone doesn't help.
