One left-field check, given the really slow network performance...   
Make sure it's not something simple, like a mis-negotiated network 
port, or a bad switch port or flaky NIC.  Reset the network connection 
from the Alpha to the switch to 100 MbE full-dup or whatever the 
appropriate setting for the hardware, and both at the switch and at the 
SRM console.  Be skeptical around the displays from any managed 
switches, and reset the port after configuring it.  (I'd expect this 
misconfiguration to show up in the packet traces, though...)
