This is a bug that we need to fix. Currently, all tests of the regular sha512crypt format use 5000 iteraions. (May be we should change that.) So, I copied the ztex self tests to reproduce this. When using --test, john first tests all hashes, then it measures the performance with just the top 2 hashes, i.e. 5000 iterations, unless you pick other hashes using something like --costs=1021:1021. Are you suggesting we should support ./john --test --skip-self-test to just measure the performance without first processing the regular self test? Frank
