A few weeks ago I ran some buildworld benchmarks on the 12-cpu sun
E4500 loaned to me by hrs:
-j12, no mpsafevm, 4BSD, invariants
6441.67 real 16670.23 user 26399.98 sys
-j12, mpsafevm, 4BSD, invariants
6371.78 real 17428.00 user 24199.93 sys
-j12, mpsafevm, 4BSD, adaptive mutexes and giant, invariants
4353.08 real 16103.17 user 17315.01 sys
-j12, mpsafevm, 4BSD, adaptive mutexes and giant, no invariants
3905.40 real 16114.54 user 13510.60 sys
-j12, mpsafevm, ULE, adaptive mutexes and giant, invariants
4359.15 real 15680.28 user 14409.26 sys
-j12, mpsafevm, ULE, adaptive mutexes and giant, no invariants
3927.60 real 15672.65 user 11076.43 sys
-j16, mpsafevm, ULE, adaptive mutexes and giant, no invariants
3880.31 real 15903.13 user 11243.04 sys
-j1, mpsafevm, ULE, adaptive mutexes and giant, no invariants
14904.45 real 12461.48 user 2670.71 sys
All tests are with a RELENG_5 kernel. System was rebooted between
each test and was otherwise idle. Adding PREEMPTION (either
scheduler), or trying to run 6.0 on this machine causes spontaneous
reboots (i.e. not panics).
If someone can think of another interesting variant, I'd be happy to
try it.
