You're correct; there is no write buffering for the http
request.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

Turn on output buffering.

Description:
------------
This code sends two packets, one of 16 bytes and one of 17 bytes.

I guess this is caused by multiple calls to php_stream_write in
http_fopen_wrapper.c: php_stream_url_wrap_http_ex

Preparing the entire request in one buffer and sending it via one call
should produce less packets (and be faster).

Reproduce code:
---------------
<?php
	echo strlen(file_get_contents("http://php.net/"));
?>

Expected result:
----------------
One packet of 33 bytes.

Actual result:
--------------
Two packets.
