It would be better to focus the actual fuzzing job. The first thing to do with fuzzing john is making john start fast. I've taken a look at it. There are two easy things here: instrumenting only a fuzzed format and john.c make john ~5x faster, removing most content from john.conf makes john ~7x faster. That's 35x boost. Solar, magnum, any other easy ways to make john start faster? Kai, could you try to profile john starting process and find out where most of the time is spent? -- Alexander Cherepanov
