VoIP- and gameserver. I previously observed my UMLs going into meditation for a split second every few seconds, but that bucking almost disappeard by taking the usual tuning steps (SKAS, sysemu, $TMP on tmpfs). Nevertheless, my UMLs are still not as responsive as i would like them to. It's not a matter of CPU or network performance. Host and guest are >=95% idle all the time, bandwidth use is far from my UML-bench- marks. I tried to renice the UML processes, but seems not to help (it's hard to measure, just the "feeling" while listening to audio or onlinegaming). Any suggestions? I enabled "PREEMPT" in host kernel. Maybe that's a bad idea? /nils. -- there is no sig. ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________ User-mode-linux-devel mailing list User-mode-linux-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel
