Date: Wed, 22 Oct 1997 10:41:00 -0700 (PDT) It's likely worse in 1.2.4 than 1.2b6 because in 1.2b7 or so I overhauled Apache's network performance. The bugs in other browsers show up particularly because they "like" webservers to send the headers in one packet, and the rest of the data in subsequent packets. Apache never does that deliberately any longer. Note that even if Apache were changed to flush its buffer after the headers it wouldn't guarantee the clients would see things nice and rosy like they want -- because TCP gets to make the decision about where packet boundaries are. So these latent bugs in browsers have to be fixed anyhow, and I'd rather not back down on this performance change. The changes were prompted by early versions of the paper which showed how poor Apache was at stuffing network packets. We're now pretty close to optimal. 1.3 won't make it any better, although it may change the behaviour a bit. 1.3 uses writev() to replace two write()s.
