I now have updated versions of these patches, which correct some inconsistencies in approach (universal use of curcpu now, for example), remove some debugging code, etc. I've received relatively little performance feedback on them, and would appreciate it if I could get some. :-) Especially as to whether these impact disk I/O related workloads, useful macrobenchmarks, etc. The latest patch is at:
http://www.watson.org/~robert/freebsd/netperf/20050425-uma-mbuf-malloc-critical.diff
FYI: For those set up to track perforce, you can find the contents of this patch in:
//depot/user/rwatson/percpu/...
In addition, that branch also contains diagnostic micro-benchmarks in the kernel to measure the cost of various synchronization operations, memory allocation operations, etc, which can be queried using "sysctl test".
FYI:
I've now committed the UMA changes from this patch.
