You can try to telnet to port 80 from some other network to the webserver using webserver's DNS name and issue "get /" request. It will spit out an error back since its not entirely correct syntax, but you can see how long that will take. This will bypass your code, and will indicate if a problem is on network/apache level. Are you using any caching engines like smarty? I dont really see how, but that may cause a problem like this. Do any other services lag in response, like SSH or SMTP or some other tcp service?.. You can also put in debug statements using microtime() into your code to see how long execution of certain components takes, and placing those calls strategically can point to some sort of bottleneck in your code. Since i've never seen the code, apologies if you've tried these things already or if they arent applicable. Check out this thread on microtime()/performance: http://www.webmasterworld.com/forum88/2567.htm As a side note on firefox plugins like firebug, i found liveheaders to be very useful in all sorts of troubleshooting, https://addons.mozilla.org/en-US/firefox/addon/3829 > > _______________________________________________ > New York PHP Community Talk Mailing List > http://lists.nyphp.org/mailman/listinfo/talk > > NYPHPCon 2006 Presentations Online > http://www.nyphpcon.com > > Show Your Participation in New York PHP > http://www.nyphp.org/show_participation.php > _______________________________________________ New York PHP Community Talk Mailing List http://lists.nyphp.org/mailman/listinfo/talk NYPHPCon 2006 Presentations Online http://www.nyphpcon.com Show Your Participation in New York PHP http://www.nyphp.org/show_participation.php
