I have a couple PHP applications running on an Ubuntu 10.04.4 server. One is a custom Yii application and one is PHPMyAdmin. Both applications recently started having very slow load times for seemingly random page or asset loads. After the issue was discovered, the server, PHP, and Apache were updated.
httping reports consistent response times around 65-75ms. This is over a LAN. Ping is <1ms consistently.
It seems to me like some sort of an issue with initializing PHP or with Apache handing execution off to PHP. Any suggestions as to what might be going on here or what a good next troubleshooting step would be? Thanks.
Edit: I just got it to hang on one JS file after creating links to 10 JS and 10 CSS files in my a script that just measures execution time, includes the aformentioned JS and CSS files, and runs a simple select query on the MySQL database.
