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?
