To affect you site's performance by removing ads, will, of course depend on the nature of the traffic to the page and what you replace ads with. Some people feel that the presence of ads can make a site look less good to users (obviously this depends on your layout and presentation skills). If you have ads that are not earning, then by removing them you could improve your site's image, hopefully with the long term goal of improving traffic to pages with ads that don't earn. If this is what you are trying to achieve, then removing ads from pages with a low CTR would probably be best.
If you have pages with low earnings per click, but lots of clicks, your focus should be on "What would you replace these with" relevant links to some of your own pages with better paying Ads may be an option here.
