Here's what it shows when openldap is running on 32bit debian etch:
did 1000 in 2second(s).
did 10000 in 28second(s).
did 100000 in 441second(s).
Something sounds wrong with those results as the unit test is linear : open/close, open/close. As long as we do not get 2, 20, 200 or something approaching, either my test code is wrong, or some server configuration is wrong.
The results on 64bit lenny are:
did 1000 in 2second(s).
did 10000 in 19second(s).
No third result, it broke and the test failed with some useless null pointer. Let's "strace -f" the slapd process on lenny :
did 1000 in 13second(s).
did 10000 in 382second(s).
Ok, will take too long and seems stalled. Will write strace output to a file "strace -f -o slapd.log".
Starts good :
did 1000 in 6second(s).
did 10000 in 61second(s).
But then...
did 100000 in 1049second(s).
I expected between 500 & 620 seconds (I hoped the jvm JIT will do its job). I used my computer in the meantime, but not that much.
Still analysing the strace output, but if someone knows what is wrong in my test...
