Neither am I. :) Squid does not flush the buffer. It's the socket code
that does that after a certain (very small) delay. Correct me if I am
wrong, but I think it is done to ensure timely response for applications
like telnet when user types characters and expects to see the effect
"immediately".(?)

Nothing published, just submitted:

http://www.cs.ndsu.nodak.edu/~rousskov/research/cache/squid/profiling/papers/

I wish it were in a better shape though -- I did not have enough time
before the deadline...

Any comments are welcome, of course...
