Subject: xboard on Mac OS X

I am running xboard on Mac OS X.  My tests show that engines running in xboard
take a huge hit in nps compared to being used in text mode.

DSjeng :
44knps in xboard
135knps in text mode

Amy :
112knps in xboard
400knps in text mode

Crafty :
116knps in xboard (more nps than amy?)
179knps in text mode using bench

Beowulf :
12knps (something has gone wrong here)
20knps (not reporting correctly?)

It does not appear that xboard is using much in the way of resources according
to process viewer so I don't know why there would be such a big hit to nps
speed.  I assume this is not normal and not an issue on most other platforms.
Has anyone else had similar results?
