Topic: Window Server 2003 and PHP Speed Issue

[darjana]

Hello,

I have a question, i have been searching for some quite time now.

I have a window 2003, 100mbit up/down dedicated server.

I have tried apache 1.3, apache 2.2, IIS, abyss web server with PHP 5.2, 5.3

When i use direct link from this webservers, i can get 1MB/s (limited by my ISP) per sec over internet. What i meant by direct link is, the link cames from directory listing without any influence from PHP.

However, i tried few php download script such as ZINA, phpIndexer, php download functions. The download speed coming from PHP(installed on same server) is roughly 30-40KB/s where as on direct link from webserver is 1MB/s.

Is there any configuration in PHP/Window 2003 Registry that need to be change so that the download speed via PHP is increased?

I have tried few suggestion from various website incl. EnableSendFile off, sendbuffersize any others without any luck so far

Thank you.

Does not sound like a Win2k3 issue at all.

Are you CPU or I/O limited on the server when running the PHP tests?

i dont think, as i run the same test, apache direct links(from directory listing) can get over 1mb/s while on php its about 20-30kb/s

is it something to do with output buffering?

PHP is executed code so by nature it will be slower than returning output from a static file. If you are CPU bound try eAccelerator to get PHP to byte code instead of a full parse every time.

Used it for many years on Windows and never had any buffering issues. Does you code output blocks of text or does it output one character at a time. One character at a time might slow you down some.
