The quad ethernet should be able to do 100 Mb/s, no? I believe the theoretical max throughout isn't too far off from that.

I think something is very wrong there. I've easily saturated 10Mbps
Ethernet with an SS2, running SunOS 4.
In fact the first machine I used that had no difficulty saturating a
10Mbps Ethernet was an SGI 4D-25G, with a MIPS R2000 clocked at 20MHz, a
far cry from the SS5/170's 170MHz TurboSPARC.
I could be wrong but I'd point a finger (or perhaps THE finger ;)))
at SSL.
