What we need is for "--test" to produce meaningful results by default, without any "--cost" option. Right now, for sha512crypt-ztex it says it's benchmarking for iteration count 5000, but the actual benchmark is for a mix of different iteration counts (and maybe a mix of different password lengths too). This is a bug that we need to fix. Alexander
