But -- if this went away, what would it do to your bandwidth? Are you 
paying by packet? If not, the only PRACTICAL difference is that if the 
pipe is full, delivery slows down.

What is the real cost is? That messages show up five minutes later than 
they would if we don't do this?

Before we play "this is a witch! burn her!" games (grin), we ought to 
figure out what the real impact is. If people want, I can post some 
stuff (no hard numbers, unfortunately) I've seen based on tweaking this 
stuff on my big machines. But the funny thing is, the biggest difference 
I see isn't network, it's disk I/O. and most of that is because of 
sendmail's design for dealing with this stuff...

I'm not saying Alex is wrong -- he's got some good points. but we need 
to quantify what those points are and what the impact is, so we can 
decide just how to move forward on this. If the impact is, oh, a 5% 
degradation in network throughput, frankly, it's not (IMHO) worth 
special casing it. If it's 30%, we need to special case it AND document 
it so people know how to tune their systems. And if it's 60%, maybe we 
shouldn't do it..

but we need to figure out what the impact is, and not guess or make
