php codeigniter slow initial load

Question

There is a site. Everything was just ok, but suddenly its working a bit strange: http://gtmetrix.com/reports/bienestarenelhogar.com/bSruWlXF (click the timeline)

It's usual apache+php+mysql

The initial request takes 15 seconds. Its using codeigniter 2.1.0. I have suspicion that the igniter is causing the problem, since the other php pages are just ok.

I currently try to get to logs, but I don't have root and can't sudo on the server. Any other way to diagnose that?

(I'm not a php guy, I'm all about java)

Any help is appreciated.

Answer 1

by enabling caching in your codeigniter app, you can boost up your app, much better. just need to append some code in project's .htaccess file.

ExpiresActive On

<Directory "/path/to/public_html/files">
    Options FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    Allow from all
