And the /proc/loadavg still seems decidedly "twitchy" for lack of a better term. It never fully settles down. And a few shells running top and tload will eventually drive it up to around 1 again. But it never stabilizes. This does not happen with the old tickey kernels. And it does not happen in any deterministic way I've seen before. I notice all the irq threads are now -51 priority. And there are quite a few of them. Plus the group of RT threads for each CPU. Your RCU Prio Booster is only pri -50 and appears to be sleeping hapily. Are there better profiling tools I could be running? ../C -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
