I'd like to see your results.
I did a similar thing on HP-UX 10 years ago, but I was looking at stress
and locking not performance, per se. At the time I found an interesting
bug where (if I recall), open(2) erroneously returned 0. (Normally file
descriptor 0 is used for stdin, and in my test case, open should have
returned a -1). Bug report was filed and accepted, but this was a rather
extreme case where I was stressing kernel file locking across NFS an
local on a multi-CPU system (either 4 or 8 at the time).
