Re: [PHP] sockets - fine tunning
Hi, I think curt is right about transfer encoding being a problem, however i feel it may not be 'the' problem. This timing issue looks like you are running into a 'blocking' kind of situation. Cosmin, Have you tried the 'Connection: close' header? Getting back to transfer encoding you might want to look at the RFC - http://www.w3.org/Protocols/rfc2616/rfc2616.html where they explain how it's to be handled. all the best Curt Zirzow wrote: * Thus wrote Cosmin ([EMAIL PROTECTED]): On Sun, 2003-10-26 at 15:30, Raditha Dissanayake wrote: are you getting any 1xx status codes from the web server? here are the full headers: Transfer-Encoding: chunked This is probably the problem.

Re: [PHP] sockets - fine tunning
are you getting any 1xx status codes from the web server?

}
This is the slowest part of my script(about 16 seconds). The server's
execution time is only 0.00064206123352051 seconds. I don't know why it
takes so much to write a string to the socket and then to read the
response. Here are the execution times:
Server StartServer Stop
1067090777.5339 1067090777.5346
Client StartClient Stop
1067090777.5303 1067090794.5286
If someone knows a way on how to speed this up please tell me how to do
it.
Thank you for your time

Try and find out where the bottleneck is by echo'ing between steps
to see where the problem is, for example:
echo time(), \n;
$fp = fsockopen($url['host'], 80, $err_num, $err_msg, 5);
echo time(), \n;

Here are the times:

And here is the code:
echo '1:'.getmicrotime(),\n\n;
while($data=fread($fp, 32768))
{
$response.=$data;
}
echo '2:'.getmicrotime(),\n\n;
I don't know what else to do ... I've changed the buffer length but it's
still the same :((
