We used macdump with Ultrix 3.1 + Uab + Cap with no problems. It took
about 25 minutes to back up a 40Mb disk on a MacII via Ethernet/Uab,
~ 25k/sec.

I recently upgraded to Ultrix 4.1, and built the ru-cap2 distribution
and recompiled/linked uab+.  Now it takes about 5 HOURS to back up 40Mb,
or ~2k/sec

AUFS is also much slower - a 630K file takes about 2.5 minues to copy,
or ~4k/sec - ftp across the Atlantic is quicker than this!

Decnet and ftp transfers are unaffected at ~ 50K/sec, so it isn't a
bad ethernet segment.

Has anyone come across similar problems ?
