ok here it is:
-----------------
around 16000 queries per second
(pthreads without process scope threads, sched_4bsd and preemption)
around 7000 queries per second
(pthreads with process scope threads, sched_4bsd and preemption)
around 16000 queries per second
(linuxthreads, sched_4bsd and preemption)
fedora result:
11900 queries per second
----
same test (same parameters) but with a update query first and then a select
query on the same key i realized worse values for freebsd:
----
around 2500 queries per second
(pthreads without process scope threads, sched_4bsd and preemption)
around 2000 queries per second
(pthreads with process scope threads, sched_4bsd and preemption)
around 4000 queries per second
(linuxthreads, sched_4bsd and preemption)
fedora result:
3920.21 queries per second?
-----------------
Because of the missing hardware i couldnt run the test again and so the
result above isnt 100% true. But the guesses should reflect the ratio of the
used engines in my test.
