There is nothing bad about this, but something that needs to be pointed out is that a wide range of devices will be accessing your website. Do you test on older, slower systems? Do you test on laptops and mobile devices? I can’t tell you how often I visit websites these days and hear the fan on my laptop kick in. (It just happened now, as I write this… someone just started a chat with me in gmail)
I’ll be honest, I don’t test as well as I should, but I do tend to notice when sites are cpu intensive because my laptop’s battery suffers greatly. I just don’t hear people talking about this topic, which concerns me a little bit.
