Gmail an Even Faster Experience Now

Over at the Gmail Blog, the Tech Lead of Gmail's performance team, Wiltse Carpenter, writes the steps his team has recently taken to improve the speed of Gmail. I personally find Gmail to be immensely faster than both Yahoo and Hotmail so it's quite interesting to hear that the Gmail team is working on making their system even faster. Below are the steps the Gmail team have taken to further improve the performance of Gmail:- "First, we listed every transaction between the web browser and Google's servers, starting with the moment the "Sign in" button is pressed. To do this, we used a lot of different web development tools, like Httpwatch, WireShark, and Fiddler, plus our own performance measuring systems. These tools all have useful features, although some are limited to working only with certain browsers. "
- "We spent hours poring over these traces to see exactly what was happening between the browser and Gmail during the sign-in sequence, and we found that there were between fourteen and twenty-four HTTP requests required to load an inbox and display it. We decided to attack the problem from several directions at once: reduce the number of overall requests, make more of the requests cacheable by the browser, and reduce the overhead of each request."
- "We made good progress on every front. We reduced the weight of each request itself by eliminating or narrowing the scope of some of our cookies. We made sure that all our images were cacheable by the browser, and we consolidated small icon images into single meta-images, a technique known as spriting. We combined several requests into a single combined request and response. The result is that it now takes as few as four requests from the click of the "Sign in" button to the display of your inbox."
