Google ad manager bogging down my site

Switch or optimize?

[johnnie]

I've been a user of google ad manager for a while, but after doing some benchmarking and diagnosis, I have noticed that the ad manager code alone takes as much time to load as the rest of my site. Is this a cue to switch or is there a way to optimize ad manager code? I have considered lazy loading, but since the code consists of many fragments, I wonder whether the additional DOM-overhead will be worth it.

Any suggestions?

it might help page rendering speed if you move the div(s) containing that javascript to just below the body tags and use css to position them correctly.
