Subject: JTR and os X macintel

Hi,

 I have now a Macintel (Apple, Intel core 2 duo) with os X (10.4.8), 2 
gigas RAM.

 Some month ago Alex told to me to compile the unix source of JTR with 
the command:
 "make macosx-x86-mmx".

 After test (./john -test) return me: 
Many salts : 923827 c/s real, 925678 c/s virtual
Only one salt: 842176 c/s real, 840495 c/s virtual

 Now, I have compiled the same source with the command :
"make macosx-x86-sse2"
now test return me :

Benchmarking: Traditional DES [128/128 BS SSE2]... DONE
Many salts:     1841K c/s real, 1845K c/s virtual
Only one salt:  1532K c/s real, 1535K c/s virtual

Benchmarking: BSDI DES (x725) [128/128 BS SSE2]... DONE
Many salts:     60006 c/s real, 60006 c/s virtual
Only one salt:  58316 c/s real, 58316 c/s virtual

Benchmarking: NT LM DES [128/128 BS SSE2]... DONE
Raw:    8503K c/s real, 8520K c/s virtual


 As you can see, it's better.

 I'm really newbie into compilation or command.

Is there others commands for compiling JTR'source and get better 
performance ?
My mac has a "core duo", is JTR use 2 cores at the same time ?

 Thanks in advance for your reply.
