I noticed that multiple packets are being sent to the network when one

is the body/file. strace
http://people.apache.org/~gregames/rhel4.cork.strace reveals that httpd
is issuing the correct setsockopt()s to enable/disable TCP_CORK. no
such problem seen on 2.4 kernels.
here is a packet trace in pcap/tcpdump binary format

Nivedita, are you aware of any bugs like this?
if you want to try this with Apache 2.x, use a file that's bigger than
256 bytes so that core_output_filter will use sendfile, but small enough
so that the HTTP headers + file will fit into one ethernet packet.
Not that I'm aware of, but on the other hand, this
code has almost entirely been rewritten since then.
I'll look into it some more...
thanks,
Nivedita
