No, it's not a failure.

BRL has measured filesystem performance improvements of 7X for
various graphics applications, and it REALLY HELPS.

I regularly see DELIVERED USER DATA in excess of 500 Kbytes/sec
sustained for > 10second bursts off of our Eagles on the SBI on
a 780.  No complaints here.

I submit that Doug Gwyn's relative ease of implementing his
System V-under-4.2 BSD package tells you quite a bit about
the relative differences.

SUMMARY.  Both System V and 4.2 are still UNIX.  System V has
lots of emphasis on good user utilities and massive
user documentation.  4.2 has emphasis on performance and networking.

If you don't need networking or performance, System V is the clear
winner.  If you have more than a few machines, networking is hard
to live without.

NOW LETS CANCEL THIS DISCUSSION -- net.unix-wizards IS FOR MORE SERIOUS
TOPICS THAN THESE INTERMINABLE PHILOSOPHICAL DISCUSSIONS.
