Yes - 10 CPU bound tasks fighting over the CPU would perform worse with PREEMPT. But for a desktop tha's not an issue be cause you usually perceive "perfomance" of the system as the systems responsivene instead of its raw computing power.
I have no raw data. I'm just experiencing that running a lot of CPU bound task while doing other thing feel slugish on trusty compared to fx. to lowlatency-kernel which problably have CONFIG_PREEMPT set. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1271742 Title: CONFIG_PREEMPT is not set.
