I have a small patch to the ULE scheduler that makes a fairly large change to the way timeshare threads are handled. http://people.freebsd.org/~jeff/schedslice.diff Previously ULE used a fixed slice size for all timeshare threads. Now it scales the slice size down based on load. This should reduce latency for timeshare threads as load increases. It is important to note that this does not impact interactive threads. But when a thread transitions to interactive from timeshare it should see some improvement. This happens when something like Xorg chews up a lot of CPU. If anyone has perf tests they'd like to run please report back. I have done a handful of validation. Thanks, Jeff
