What web server are you using?  Is it Apache, lighttpd, php daemon, etc?

If it is anything but directly talking to a php daemon, you must take into
consideration that the parent web server does not hand off processing to PHP
until it has received the entire file.  At this point is when your timer script
starts working.

So, what is receiving the file?
