Hakura:

I ran a test over a T1 line connecting a VAX8600 running ULTRIX and a 
VAX750 running Wollongong.  Both machines with DMR11 interfaces.  The
MTU's for both interfaces is 1248.  I noticed that the round trip delay
I was getting was less that 30 ms from 18 bytes to 1248 bytes, then as
I continued increasing the packet size it jumps to around 6 sec.  This
only happens when we do it with a machine running Wollongong.  When I 
tried from ULTRIX to ULTRIX the jump is about one order of magnitude
instead of 200 times.
