Hello,

The tests were made on a Intel Corei3 with HT (2 cores - 4 threads - this
is why all tests are made with 2 processes, to see if they run on different
cores).

Here are some preliminary results:

1) openssl speed rsa512 tests - 2 processes at the same time - 30 runs

As you can see, in case the ht_enable option is activated, the signing
times are more constant. In the first case it all depends on luck, if they
are scheduled on different cores.

2) apache compilation (make -j2) - 30 runs. This runs at most 2 processes
at the same time.

28.193s  29.319s 28.340s  29.592s 28.794s  30.303s 28.361s  29.557s 28.497s
29.269s 28.063s  30.575s 28.337s  28.715s 28.963s  29.569s 28.571s  29.435s
28.804s  29.460s 28.672s  30.180s 28.143s  29.207s 28.334s  29.855s 28.939s
29.253s 28.407s  29.392s 28.202s  29.767s 27.882s  28.796s 28.309s  29.991s
27.976s  29.432s 28.550s  30.455s 28.096s

As you can see, the differencess for building apache are small (~1,5sec =
5%). This is because a building process isn't so CPU hungry, it often waits
for I/O.

I will come later today, with a bash script for openssl tests, for those
who want to run it.

Thanks,
Mihai
