Removing the check for vcpus on the runqueue may actually be functionally equivalent to removing the check altogether. I guess part of the thought might be that we don't want to have a single cpu running for a really long time without other cpus getting a chance to run at all. But in order for "weight" to have any meaning, sometimes a cpu will have to get a long time to run. What workload are you running -- is it just while(1); loops? _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
