Ron,

  I'm confused. Is there something to back this opinion up? Which machine or
implementation are you discussing? For my own view of things TURBOchannel is
the fastest shipping desktop interconnect in the market (with internal designs
of network options that have sustained over 80MB/s under software control).

If there are specific examples of issues you've seen with performance I'd be
interested.

The platform breakdown looks something like this:

	12.5MHz  50MB/s				25MHz  100MB/s

	DS5000/20				DS5000/200
	DS5000/25				DS5000/240
	DS5000/33				DS5900
	DS5000/120				DEC3000/400 (actually 93MB/s)
	DS5000/125				DEC3000/500
	DS5000/133

If you have questions about specific platform implementations (the numbers
quoted are theoretical peak bandwidth, the highest I've seen a 12.5MHz system
run is ~44MB/s and a 25MHz system is ~82MB/s). And the DS5000/200 started 
shipping in April of 1990.

I hope that clears things up.

				Thanx,

ps. I haven't included the VS4000/60 or VS4000/90 on this as the TURBOchannel
    on those systems is a bridge adapter which is bounded in performance by the
    bus on the system module.
