Re: [PHP] Scripts are fast locally, but slow on remote server
Are you relying on autoload or anything of that nature to load in class files, perhaps?

If it were a name server issue, I would expect the slowdown to happen regardless of which page I load first. So, I guess to be more specific, the slowdown happens the first time I load one of my PHP scripts on this site, not the first time I access the site. Try it with just this in a .php file: ?php phpinfo();? Is *that* slow the first time? Also try it with: ?php echo Hello World!? Is that slow the first time? -- Some people have a gift link here.

For whatever reason the first invocation waits for a time-out, which could take a while, but the second gets an near-immediate response as the negative answer is now cached. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Connect to a database? Ping a server? X? :) If it's connect to a database, does it use the 'name' of the server or the ip address or is it localhost? Does it do lots of queries? -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

And your script does not cause any dns lookups? If it were a name server issue, I would expect the slowdown to happen regardless of which page I load first. Not necessarily - it would depend on what is being looked up. So, I guess to be more specific, the slowdown happens the first time I load one of my PHP scripts on this site, not the first time I access the site. Have a look at which external services you use - database, nameserver, ldap etc. I'm assuming an initial loop is out of the question? Also, check memory status - if the server is very heavily loaded, and your stuff isn't in memory, it could take time to page it in. 10 seconds is a long time, but ... /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
