PHP concurrent processes

[ElectroSoft]

Hello guys,

Well, if I have a PHP script which runs for about 10 seconds on the server before returning the page to the client. How many concurrent processes can I have?!

// Code
for($i=0;i<10;i++) {
//Do something... few sql queries
sleep(1);
}
// End of code

Do I need a very powerful server to handle like 100 to 500 clients requesting the page in the same time?!

what are the factors?

thank you

What do you have running that takes 10 seconds at a time? If it is queries, you should look at optimizing the query statements.

maybe a look into the "Do big PHP scripts demand system resources [webmasterworld.com]" thread might be of help in analyzing the time your script needs to run.
