Why is speed vital?

Because

� 40% of people abandon a website that takes more than 3 seconds to load.

� If an e-commerce site is making $100,000 per day, a 1 second page delay could potentially cost you $2.5 million in lost sales every year.

� Google Cares (TTFB <=200 ms)

There are ways to speed

things up

the options
