This exact problem causes havoc if you have many slow clients on slow networks (gprs).

We actually had this problem, and to confirm #8. its *really* "hard to catch". We actually had a >80% unsuccessfull connection attemps.

I cannot believe Apache ships with TCP_DEFER_ACCEPT on 1 sec, or even enabled at all. I don't see the possible gain.

ref: varnish had it enabled for a while but they disabled it too [1]

Can ubuntu change the default config to include:

AcceptFilter http none
AcceptFilter https none
