5970 slow?

[uzomoshi]

This is my benchmark 825/1010. I had to set --cpu-accel=240 instead of 800 because every run was killed. I guess due to insufficient memory (I got 1Gb ram). Results are comparable though and the small difference may be well due to cpu-accel.

So you were right, of course! salt+pass accounts to about 7% penalty, 200k hashes account to about 17% penalty and they add up to about 25% penalty I was observing.

Concluding, can you point out how to maximize a sha1 salt+pass attack?
Lite is not an option, I also tried the trick of putting salt in the mask (-m 100 ... <salt>?a?a?a?a?a), hoping -m 120 was optimized for many salts, but it just runs 10 times slower. 830 looks like the top without overvolting (and I don't want to). So, the only try looks like going -n 800. Do you know if I need more ram and suggest how much?

Thank you!!
