How's I/O on this thing?  Would use as a fileserver be a shameful 
waste?

HP has worked hard to optimize system performance on the Series 700
instead of focusing on a few small benchmarks.  The June '91 release
of HP-UX will support a high-performance EISA SCSI adapter providing
a 10MB/second (burst) transfer rate to the disk.  When combined with
HP's differential disk storage system, this is among the highest
performance SCSI subsystems available.  For example, based on numbers
from the SPARCstation2 Performance Brief, the Series 700 provides 50%
more throughput on sequential disk accesses.

The Series 700 provides superior LAN performance as well.  In fact, our
tests show NFS, Berkeley Stream Socket, and FTP transfers at up to
1000 KB/second, nearly the theoretical maximum of 1200 KB/second for
IEEE802.3 LAN transfers.  Of course, these results will vary depending
on the CPU load at the server, but the Series 700 has plenty of CPU
power to solve that problem!
