We've had 8.0 running on a pronet-80 to ethernet gw for about
seven weeks.
It hasn't crashed or lost it at all. 
Works fine.  I did have to restart it once 5 weeks ago
when a static ram parameter changed.
Proteon did a fine job on the installation, redid  our whole
static ram config for us on it.  Whether your installer will
come shoot me for telling you, I don't know.

End to end throughput is at least double what it was in 7.4.
Some numbers for using 8.0:
sun 3/260 on ether to sun on pronet-80 290 kBytes/second
sun 3/260 on pronet-80 to sun on ethernet 210 kbytes/second

With streams running both ways, the GW handles
1400 packets/second.  This is about half 'large' packets (1K for ftp data)
and half small (64 byte ack packets.)  It is not certain whether
this number could be larger when more hosts get involved.
Maybe I'll know later.

I haven't yet accurately measured aggregate throughput,
but we can get at least an effective 2.3 mbits/second through it
into host machine memory, using TCP.  This is the effective
data rate, including acks.  From the way timing results look,
I suspect aggregate from multiple hosts is larger.
