The last few kernel revisions seem to have affected latency in certain areas. This is most obvious in hot keying from the GUI screen on vt7 to a plain text mode login on vt1. I should be almost instantaneous. I was in past months. Its now taking 3-4 seconds. That really really noticeable.
Yikes, where are you getting your kernels? I'm on OS 13.2 64 bit, and using kernel 3.16.7-7-desktop.

Switching is instantaneous.
Well, given that its not any of the scheduler option, since I've tried them all, and assuming its not something else in the delta between 13.1 and 13.2, then it looks like my issue of the kernel being responsible is a reasonable assumption.
I'm going to to get hold of 3.16 series and see. .... ..... ...... Well, it seems the current repositories for 13.1 just pull the latest GIT or have the 3.11 that was on the baseline distribution.
It looks like my weekend project, if I chose to accept it, is looking though the change logs to see what's in the 3.19 that might account for this.
Sometimes newer kernels require userspace app changes to go with them. I doubt if many people are testing 3.19 kernels with oS 13.1 But you are not the only one: http://markmail.org/thread/y6jgpfkclc6akpxy Note that in the above the 3.19 kernel seems to have broken all USB external storage for now. Bruno looks like he is in the process of fixing that. http://markmail.org/message/23rfrmyg45xaydrq Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
