Re: [PHP] CPU usage @5% during 2 minutes
HLP! This becomes more and more strange. Aftar I was really happy, that the code runs fast again, the customer sent an e-mail that is still slow. So I logged in into his network and everything was ok for me, but when they tried to use the program, I still saw (using top), that the CPU usage is still @5% (highest value). So I began to use the debug log of apache, and see what happened (LOOK AT THE LAST NUMBER, WHICH SHOWS HOW LONG THE SCRIPT RUN): In this case I was using it from the localhost: 10.36.0.5 - - [20/Oct/2004:14:27:25 +0200] GET /form.php?op=reprint_form_sel HTTP/1.1 200 1478211 - Links (0.99; Linux 2.6.8-1-686 i686; 80x24) 17970 3 In this case I was using it from another host in the network (actually the proxy): 10.36.0.2 - - [20/Oct/2004:14:23:33 +0200] GET /bizerba/form.php?op=select_form HTTP/1.0 200 1473492 - Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 GNUTLS/0.8.12 17969 7 In this case the some other client was using it from the network: 10.36.0.2 - - [20/Oct/2004:14:33:23 +0200] GET /bizerba/form.php?op=select_form HTTP/1.0 200 1473492 - Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) 17970 36 No, it is not the network, which is slow! Is it possible, that all clients (except me) are accessing it throug a proxy and some proxy settings were changed, so the webserver is running slower? (of course this wouldn't excplain the fact, the the code ran slower on other machines too). David -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] CPU usage @5% during 2 minutes SOLVED
Hi all! After 2 weeks of sleepless nights and visiting the customer three times (once on saturday) the problem is solved. The thing was: The new, 20 year old administrator guy set all clients to use the local network via the proxy. And the proxy wasn't able to handle the approx. 1,5MB huge web pages. So after ensuring me two weeks ago, that their local network is perfect they'll get a nice little bill. Thank at all.

[PHP] CPU usage @5% during 2 minutes
Dear php list! I have a real big and strange problem I ran into few weeks ago. One of my clients complained, that the intranet software began to run very slow, almost unusable. Since then I have almost tried everything to get the thing work. The facts: On P3 architecture systems (I have tried 3, including the server at the clients office) runs very slow and with about 0-5% of CPU usage. The code needs about 2 minutes to get completed. On a P4 it is ready in 2 seconds with 100% CPU usage. I have placed a debug function into the code. It is a string that collects unix microtime each time within the loop. This loop has approx. 10k cycles. The loop does nothing than echoing a row. Sometimes there is a 4 second gap between two cycles, sometime only a few microseconds. The original system was installed from Debian Woody, but the problem appears on a Sarge system, and when using apachephp compiled by me. No configuration file fine tuning seems to work. The most strange thing is, that the problem appeared at a time, when no changes to the program was made. ANYBODY RAN INTO SOME SIMILAR THING? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] CPU usage @5% during 2 minutes
The sample code (in seperate, this piece of code runs with normal speed,
but it is this part which runs slowly when executed as a whole,
everything else is fast):
$sqlquery = SELECT sh_Number, sh_Status FROM service_sheet ORDER BY
sh_Number DESC;
$result = mysql_query($sqlquery)
or die (mysql_error().brbr._ERROR_QUERY.: .$sqlquery);
echo SELECT onchange=\this.form.service_sheet_worknum.value =
this.value;\ class=\service_sheet_list\ name=\service_sheet\;
while (list($shID, $shStatus, $shWNum, $custName) =
mysql_fetch_row($result)) {
switch ($shStatus) {
case 1:
$option_class = status_1;
break;
case 2:
$option_class = status_2;
break;
case 3:
$option_class = status_3;
break;
case 4:
$option_class = status_4;
break;
case 5:
$option_class = status_5;
break;
}
echo OPTION class=\$option_class\ value=\$shID\$shID/OPTION;
}
echo /SELECTnbsp;nbsp;nbsp;nbsp;._OR;?

RE: [PHP] CPU usage @5% during 2 minutes
How any rows are you pulling from the database?
aprrox. 12.000 but there are only around 50-100 new rows at a maximum
within a day, and there were almost as many before the problem appeared.
What's the very last part of the code: .$_OR?
There is a switch, some echoes and a db_close;
Have you tried this code in a separate script to test it's performance
individually?
Yes, then it performs good.
This seems to be strange and irrelevant to me, because placing a
$tmpsting .= microtime().br\n; into each loop and then echoing it
shows, that there are randomly processing gaps between two cycles when
running as a part of the whole.
