Wikia: fast pages retain users
At OSCON last week, I attended Artur Bergman’s session about Varnish – A State of the Art High-Performance Reverse Proxy. Artur is the VP of Engineering and Operations at Wikia. He has been singing the praises of Varnish for awhile. It was great to see his experiences and resulting advice in one presentation. But what really caught my eye was his last slide:
Wikia measures exit rate – the percentage of users that leave the site from a given page. Here they show that exit rate drops as pages get faster. The exit rate goes from ~15% for a 2 second page to ~10% for a 1 second page. This is another data point to add to the list of stats from Velocity that show that faster pages is not only better for users, it’s better for business.
