Given that the majority of FreeBSD users will be pulling code from the internet, this seems to be the most relevant test. > The appropriate way to test this > would be to create a binary out of the md5 routine in csup, and link it > alternately with libcrypto and libmd.

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 _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
