“You can’t hurry love,” sang The Supremes. But Aideen NasiriShargh, lead software engineer at Zoosk, disagrees. When it comes to online dating, it’s all about optimizing TTF.

That’s “Time to Flirt,” in case you didn’t know—how long it takes for a user clicking on a Zoosk link (in an email, say, or in a Google search) to land on another user’s profile and begin interacting with them.

In his presentation “Love Can’t Wait!” at FutureStack16 San Francisco, Aideen explained why: “Because a 1-second delay in page load time causes a 7% loss in conversions, 11% fewer page views, and a 16% decrease in customer satisfaction.” And he acknowledged that early attempts to reduce TTF (such as implementing a delay in loading images, and prefetching search results) weren’t as effective as they needed to be.

Deploying New Relic inspired Zoosk to try something different: cleaning up its code. “I deleted 20,000 lines of code—10% of our codebase—and our page load time improved by 15%!”
