Mod_pagespeed slowing my site down?


I have PageSpeed beta enabled on one of my sites and I noticed a lot of website traffic from a Dreamhost IP with mod_pagespeed in the user agent. Is this normal? I don’t think my site would generate as much traffic per day without this so it seems a bit wrong.


Yes, that’s normal behavior for mod_pagespeed — it will internally download and “inline” some resources, including CSS, Javascript, and image files, when doing so is likely to speed things up for the viewer.
