Subject: Re: [PHP-DEV] readfile() memory usage
From: ircmaxell@gmail.com (Anthony Ferrara)

I know it doesn't really fit this problem in general, but I figured I
would point it out.  Lighttpd introduced a brilliant concept by
letting the server serve that file directly.  Basically, instead of
using readfile, you would just send a header: X-SendFile: $filename...
 It's available for Apache (as a module:
http://www.jasny.net/articles/how-i-php-x-sendfile/) and NginX as
well.

The benefit is that the file never needs to be moved around in memory,
it can be directly mapped to the network card by the OS.

Just pointing it out (although it doesn't directly apply to the memory
usage, it solves the problem differently, and better)...
