This is going to help you pin-point the timing issue.
Is it taking a full minute to read/buffer that data?
Or does it all get sucked down and then a minute is lost?
Or, is it a minute lost and then all the data rushes through?

How certain are you of the logging on that Java server?...
I've had a similar situation, though we were fighting over 10 seconds
instead of 60, where the other vendor's timings and ours never did
match up.
I'd like to report that we solved the problem...
But since the solution involved ditching that vendor and choosing
another one, I don't think you want to hear about it... :-v
NOTE:
We are a Un*x shop; They were a Windows shop.
Near as I can tell, that right there was the source of the problem...
PS
We went through a lot of hoops with the first vendor to try and work
things out, including installing their application on a Windows server
in our rack (ugh!), to get network lag time to minimum.
They had Admin login on the Windows box, and we told them to do
whatever it takes to get it fast.
We spent a FORTUNE on that box, and waay too much time trying to
make things work out with them. Bent over backwards to make it work
before giving up on them.
It was very frustrating, because they kept reporting that their box
was sending things out in X seconds, and we kept seeing 3*X seconds
for how long the data took to arrive. :-(
They kept asking for our source code, and it took them weeks to grasp
that this was all there was to it:
$start = microtime();
$data = file_get_contents($their_url);
$end = microtime();
For some reason, they like it much better when I added a loop such as
you have, even though that only made things worse...
We never did agree on how long it took their box to do things -- I
couldn't even run their test programs locally on that Windows box and
get the same numbers they did...

[PHP] Socket Functions in PHP
Hi all,
I suspect I'm having problems with socket functions within my PHP
application running on Red Hat 2.4.21-4.EL #1/PHP 4.3.2/Apache 2.0.46.
Below is a sample code listing:
function sendRequest($strRequest) {
$parser = NULL;
$logman = new LogManager();
$resource = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
$logman->append("Connecting to OLS Server...");
$socket_conn = socket_connect( $resource, $serverIP, $serverPort );
if( $socket_conn ) {
$logman->append("Connected to {$serverIP}:{$serverPort}. Sending XML
request...");
socket_write( $resource, $strRequest );
$logman->append("XML request sent. Waiting for XML
response...");
$document = "";
$data = socket_read( $resource, 1024 );
while ($data != "") {
$document .= $data;
$data = socket_read( $resource, 1024 );
}
$logman->append("XML response received.");
$parser = new OlsResponseParser;
// parse the received document using our parser
$parser->parse($document);
}
if ($parser != NULL) {
return $parser->getOlsResponse();
}
return $parser;
}
The following listing is from the logs I have created...

+---+-++
As you can see, there is a lapse of more than one minutes between
LogId's 40 and 41, which is very slow on a production environment. The
script above acts as a client to another application server listening on
a remote port, running on Java. What the remote application reports is
that it receives the connection request, receives the request data, and
transmits the response data at the same second, while my application
receives the response one minute after the request was sent!
Other implementations in the enterprise using different architectures
and technologies/languages do not experience the same issue as my app does.
Please help. Comments, suggestions and thoughts through the group or
private mail are deeply appreciated.
Thanks!

[PHP] Flash XMLSocket object and the PHP socket functions
I am currently thinking about how to implement a realtime chat using the XMLSocket functionality in Macromedia Flash 5 using the PHP socket functions. Here's a quote from the Flash 5 online help: --- begin quote --- Using the XMLSocket object To use the XMLSocket object, the server computer must run a daemon that understands the protocol used by the XMLSocket object. The protocol is as follows: XML messages are sent over a full-duplex TCP/IP stream socket connection. Each XML message is a complete XML document, terminated by a zero byte. An unlimited number of XML messages can be sent and received over a single XMLSocket connection. The XMLSocket object is useful for client-server applications that require low latency, such as real-time chat systems. A traditional HTTP-based chat solution frequently polls the server and downloads new messages using an HTTP request. In contrast, an XMLSocket chat solution maintains an open connection to the server, which allows the server to immediately send incoming messages without a request from the client. Setting up a server to communicate with the XMLSocket object can be challenging. If your application does not require real-time interactivity, use the loadVariables action, or Flash's HTTP-based XML server connectivity (XML.load, XML.sendAndLoad, XML.send), instead of the XMLSocket object. To use the methods of the XMLSocket object, you must first use the constructor, new XMLSocket, to create a new XMLSocket object. --- end quote --- Does anyone have any knowledge of similar projects/attempts to create a server in PHP that would be able to talk to a client that uses the Flash 5 XMLSocket object, or would anyone care to provide some pointers to other resources about it? I've never tried to write a server, but this might solve quite a few problems that I encounter on a day-to-day basis. Http really sucks when you try to do anything vaguely more complicated than a mailto form, seeing that it is a stateless protocol . . . and Flash 5 could fill that gap for the stuff I'd like to do at least.

Re: [PHP] socket functions
Did you read the Manual? >From PHP Manual = socket_set_blocking Description int socket_set_blocking (int socket descriptor, int mode) If mode is false, the given socket descriptor will be switched to non-blocking mode, and if true, it will be switched to blocking mode. This affects calls like fgets() that read from the socket. In non-blocking mode an fgets() call will always return right away while in blocking mode it will wait for data to become available on the socket. This function was previously called as set_socket_blocking() but this usage is deprecated. = There is note that says it does not work with PHP4/Win32. I may need to check BugDB to find out status of this problem. I compile with --enable-sockets, so I don't know if it available without it.
