[PATCH] new test for lock performance
This test attempts to asses the performance characterists of various mutex
strategies we use in APR. It resembles a test from W. Richard Stevens
in his _UNIX Network Programming: Interprocess Communications_ Vol 2,
Second Ed., Appendix A. In these tests a number of threads are created,
and each thread iterates MAX_COUNTER times (currently 1 million).
In each iteration through this loop, the thread will lock a mutex,
increment a counter, and unlock. The total time taken (in usec) is then
printed. I have some more optimizations that will be tested for efficacy
using this test.
I'm currently only supporting these mutex types:
apr_lock_t, INTRAPROCESS/MUTEX
apr_thread_mutex_t
apr_lock_t, INTRAPROCESS/READWRITE
apr_thread_rwlock_t (only used as an exclusive writer)
** I would encourage everyone to compile and run this test, and send
the results to me privately/off-list (along with a description of your
system: platform/revision chip arch, etc...). I will then compile the
results and post them back to the list.
[I've inlined the new test, and also attached it. The patch will simply
enable it in the Makefile]
