I worked a contract where we slaved to get our load time down to some respectable number, and then they launched the site and load time was multiplied by just the analytics software (it was a company website, they weren’t running 3rd party ads).

How demotivating. It was time to start thinking about moving on anyway, but I basically stopped trying to pursue contract renewal at that point. All that work (and uncomfortable meetings) so Google could triple our load time.
