I was going to say "not much" but I just checked raw-sha1 and apparently it's 33% faster. I'm not sure how that happened, from memory the code changes only boosted it by like 10-12% (and this CPU does not support XOP or other stuff that Solar added optimisations for). $ ./john-jumbo5 -t -form=raw-sha1 -conf=legacy.conf Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE Raw: 8416K c/s real, 8416K c/s virtual $ ./john-magnum -t -form=raw-sha1 Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE Raw: 11110K c/s real, 11184K c/s virtual magnum
