Which is silly in it self. Why even search the node 
database? After all, the MOP request holds all the 
information needed to serve it. RSX don't do a lookup at a 
boot request. It just serves it.

But even so, it is surprising that even a fairly modern VAX 
can't keep up with a PDP-11 here.

Funny thing: a real VAX (VS 4000/60) can't keep up with an 
EMULATED PDP-11 running in a Raspberry Pi ;) I had to disable 
service in the emulated PDPs or else they tried to serve the 
OS to my 4000/90 ;)

Really?   Are you sure that does not have more to do with the fact that
the VAX only has a 10M NIC where as the Raspberry Pi has a 10/100 NIC.
I have not clocked the virtual 11/83 on my RPI but the virtual VAX runs
at about 1.6 VUPs.   That would put it in the VAX-11/785 class - ie not
all that fast...
