I've just added it to the command-line I was using yesterday, and wow:

real    1m2.875s
user    4m49.672s
sys     0m21.988s

Previous best was 1:16, now it's 1:03.

Same number of passwords cracked (1709703).

The post-loading time was only 33 to 36 seconds (it varied a bit across
the 8 processes), which I think is close to Fred's.  But the loading is
slower.  In fact, there's a delay of a few seconds between the "Loaded"
line and the start of cracking - what's happening there?  Reading of the
wordlist?  But IIRC I saw similar delay at that point even with mmap.

Why is -enc=raw not the default, again?  Especially if common wisdom
appears to be to use it every time unless there's a reason not to.
