Having looked at various implementations of crypt() and crypt_r(), I can't think of a reason why there would be any significant difference in performance. On systems like FreeBSD, crypt() is just a simple wrapper around crypt_r():

If there would be any difference in performance, it would also be astronomically small compared to the computation time spent by the cryptographic hash functions themselves.
