The proper way to test the libmd vs libcrypto versions of the md5 routines is to use a profiler. Of course, one might ask the question on how the use of libmd effects the majority of FreeBSD users (ie., not FreeBSD developers). Does the majority run csup hourly? Daily? Weekly? For a utility seldomly run be the majority of FreeBSD users, Doug, you seem to be wasting Marius's time. -- Steve
