Hi, I've got some more information: the kernel itself is not preemptiv, but there are some preemptiv settings set. But I used an alternative preemptive fedora kernel and found only small changes. What I found: - In vlc I have to deactivate overlay-mode - In Parole I have to set "No Xv" instead of "X11/XShm/Xv" in settings, videooutput.
Parole works better than vlc and is at around 1-2 updates per second, which is far better than every 10 second, but still not really watchable. Perhaps there is still some wrong setting on my computer (caching the video-pictures?) or my server is at it's limit ... Though there are still 3Gb (of 6Gb) free, CPU is working at 10-30%, ping is nearly all the time lower than 0.5ms. Thanks so far, Are there any settings or players you prefer? Is a [email protected] too slow as server, which impact is on the graphic card (though I have no problems locally) Harald 2015-09-07 16:59 GMT+02:00 Robert Dinse <[email protected]>: > > Do a uname -a on the box and see if it has PREEMPT in the result > string. > If it does then it is and then I'd start looking at resource usage on the > box > or possibly network latency issues.
