A month ago, after having installed Suse 11.3, I already experienced that Linux hesitates to use all four cores, say, it puts the first four processes on the first core etc., never used all. The day before yesterday I made a complete update, and I noticed something about a "kernel optimised for laptops". That made me already worry (what could this mean other than energy saving and such stuff --- while I need full power), but I hoped the best. However since since it keeps at least one core idle, apparently independent of how many processes you are running (that is, long time processes --- shorter ones apparently get scheduled on the idle processor). And actually most of the time 2 cores (from the four) are kept idle, so that for example 8 long-time processes are cramped on 2 cores!
Are they also CPU-bound?
Hope somebody can help. I can not imagine that Linux can't handle a quadcore processor!
No, it works very well here, I have several multi-CPU and multi-core boxes running 11.3 -- Per Jessen, Zürich (8.4°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
