Thanks to all who have responded. 

Let me clarify what I can.

The two EPICS releases, as well as vxWorks kernel and everything 
else, are actually on two separate hosts.

The network problem occured to me too. I have swapped hub ports for 
the two hosts in question and can see no difference in time.

As for the changing of numbers, I've had that problem when I take 
an ioc and change its IP number. In this case, however, the ioc 
maintains the same number. All that changes is the host it looks to 
for the code. Also, in the other case, waiting a while for the TCP 
timeout fixed the problem. Similarly, switching back to the old 
number would require another timeout to return to normal. In this 
case, it's always slow on the new host and always fast on the old 
one.

As for rsh or ftp, how exactly does one tell? I've booted my iocs 
the same way since the EPCIS class at APS over six years ago. I 
didn't know the protocol then, and I don't know now. All I know is 
that it works.

Oh, one last thing: I'm not certain about the BSP. The new vxWorks 
says it's 5.2 and the Kernel is WIND 2.4. I don't know what the old 
one was, but I'm pretty sure it was the same or maybe 5.1. The boot 
ROMs have remained the same.
