I guess it's more likely because of overscheduling for small crtitical sections, did you counted the total number of context switches? I guess there will be a lot more with your patch applied. That regression is a showstopper and it is the reason why I've suggested before to add a CONFIG_XPMEM or CONFIG_MMU_NOTIFIER_SLEEP config option to make the VM locks sleep capable only when XPMEM=y (PREEMPT_RT will enable it too). Thanks for doing the benchmark work! _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
