The patches are basically ports of OpenSolaris' code and should improve write performance and stat() syscall performance. The patches are available for testing on 9-CURRENT and 8-STABLE.

Interesting information for the first patch:

of: "50% Improved OLTP Performance, 70% Reduced Variability, 200%
Improvement on MS Exchange"

and for the second:

- lowered mutex contention in the read/writer lock (rrwlock)
- several bugfixes

Interested users are invited to test them so they can be imported as soon as possible!
