While we're just shooting the breeze, there is still something to what you're saying here. It's a long held complaint that Google's ad/analytics/tracking scripts slow down page load/page render times. It's also long held that Google prioritise speed in rankings. My guess is that they'd be excluding their own scripts and ad load times as part of that page load calculation, even though that is not a genuine result and would down-rank pages that utilise competitor ad platforms.
