Unfortunately, you give me so little information that I have little to
say in return.

Was AIPS rebuild for the new RedHat?  What compiler was used?  What
version of RedHat is it?  Are you runnning on a computer locally over
over the net - i.e. with a compute server and a local desktop as the
display server?  Is XAS running on the display server or on the
compute server with only $DISPLAY going to the desktop display server?
This last would be incredibly slow.   What sort of interconnection are
there between computers - is the Internet socket being used and having
to go to some remote computer somewhere as the name server?

Try

aips tv=local 

as see if things like TVLOD and TVTRANS (verbs inside aips itself) are
slow.
