That's the  point that the technical people were making at the RFP 
meeting (actually, mostly me and Brendan  Netscape). People 
don't want to know how many 300 byte documents they can server per 
second- they want to know how many big I Internet users can be browsing 
at any given time without their having to buy a new machine or upgrade 
their connection. 

As you say, the protocol is still the problem; when I was visting with 
Dave Raggett at HP-Labs, I was able to get TPS rates out of a 
trivial HTTP-NG mockup on a spare machine that no-one else wanted that
far exceeded the best numbers I can get out of massively tweaked servers 
running on far faster machines. There's a limit to how fast you can make 
a steam engine go... Dammit Jim - you canna change the laws of physics.
