time cvs rdiff -rRELENG_2_1_0 bin >/dev/null

without mfs
      96.41 real        35.85 user        24.41 sys
with mfs
      70.14 real        35.62 user        24.44 sys

Unfortunately cvs(1) use tmpnam(3), which always try /var/tmp
(P_tmpdir from stdio.h). Nobody mount /var/tmp with mfs. Can we change
P_tmpdir to "/tmp/" or use _PATH_TMP from paths.h in tmpnam(3)?

/usr/include/stdio.h:
/* System V/ANSI C; this is the wrong way to do this, do *not* use these. */
#ifndef _ANSI_SOURCE
#define	P_tmpdir	"/var/tmp/"
#endif
