Hi,
If you can package up some kind of test or analogous workload that I
can run, I'd be happy to take a look at profiling it on MP hardware.
Should be possible. Btw. Has setting kern.threads.virtual_cpu to a different
value effect for running programms or just started ones ?
P.S. I assum

Hi,
It would be really great if we could find "workload owners" who would
maintain easy-to-run benchmark configurations and also run them regularly on
a fixed hardware configuration over a long time publishing results and
testing patches. Kris has done this for SQL benchmarks to great effect

Now that the goals of the SMPng project are complete, for the past
year or more several of us have been working hard on profiling FreeBSD
in various multiprocessor workloads, and looking for performance
bottlenecks to be optimized.
We have recently made significant progress on optimizing for MySQL
