DEQNAs are recommended to be at the highest priority bus 
positions to ensure that no receptions are lost.  Two of them can 
use up 2*10Mb/s*1B/8b = 2.5MByte/sec of the uVAX-II's Q-Bus (a 
majority of it).  Of course, the Ethernets are not 100% loaded, 
but there is some DMA overhead that can help make up for it.
When you buy the fastest Q-Bus Ethernet adapter, you have to make 
these sacrifices...
