The AXPpci isn't the fasted. I rate it as the entry level to the
DEC-Alpha platform for the monetary dis-advantaged ;)

Nevertheless, the DEC benchmarks were obtained using 1MB-15ns
cache. I have sourced a supplier but haven't bought them yet as I was
hoping that the prices are still on the move down (around DM330 ex tax
from a supplier in Berlin).

Besides this, it performs quite nicely as a fileserver on the LAN.
Its runs the mail exchange, news-server, web-server, web-cache,
msql etc. pp. and was very reliable so far. I use the intel-boxes as
terminal servers and workstations 8)

I wouldn't mind running XWindows but there are no XServers available
supporting PCI-VGA graphic cards on netbsd/alpha - doh.
