Here are some amazing website performance statistics highlighted by Joshua Bixby at Strangeloop in his recent 1 to 1 Media blog post.

I’m calling out a few of the statistics here, but read his entire post for all the glorious detail and links to the research that he has provided.  As Joshua points out, “when it comes to online revenue, every millisecond counts.”

• A recent Akamai study found that 57 percent of site visitors will bounce after waiting 3 seconds or less for a page to load
• Microsoft deliberately slowed down its Bing site by two seconds, which led to a 4.3 percent loss in revenue per visitor
• Shopzilla famously sped up site, accelerating its average page load time from 6 seconds to 1.2 seconds. Without making any other outward changes to the site, Shopzilla experienced a 12 percent increase in revenue and a 25 percent increase in page views
• Amazon performed its own page speed optimization and announced that, for every 100 milliseconds of improvement, revenues increased by 1 percent.

I love that last one.
