On my 16 core opteron I have to do -j32 or sometimes -j64 to be using 
everything all the time, is this normal? If I don't do this it won't be 
pegged at 100% all the time.

I assume using a ramdisk would help with this? I wouldn't want to do a 
SSD as I assume it would excessively wear by doing compiles.
