pagespeed.config default location and additional copies in an easy apache directory

[Fabio Fatuzzo]

Some time ago I kindly requested my host provider to add mod_pagespeed in my Apache configuration. Best decision ever.

However I am wondering which one of the following pagespeed.config files I found through the WHM configServer Explorer is the main (or right) one in order to configure that module:

Score: 0005 File: [Home]/usr/local/apache/conf/pagespeed.conf
Score: 0005 File: [Home]/home/cpeasyapache/src/pagespeed/mod_pagespeed/pagespeed.conf
Score: 0005 File: [Home]/home/cpeasyapache/src/pagespeed/mod_pagespeed/etc/httpd/conf.d/pagespeed.conf

My guess is the first one. When I edit the first one however the other two are not affected so I wonder why there are three copies of the same file and if I can safely delete the two additional copies located in the easy apache directory.

Thanks for any help
