Independent studies by Google and Microsoft’s Bing team were seeking to understand the impact of latency on user behavior. Their studies generated surprising results. The companies presented their results jointly at the O’Reilly Velocity conference in San Jose CA in May of 2009.
They wanted to assure their investment in systems to deliver search results and advertising was indeed based on user results, and if possible, business impact. The fact that these two companies came to very similar conclusions after their independent experiments brings a lot of credibility to their joint conclusion. The result of their research: latency matters.
