It was a couple of days ago when I noticed something strange in my RSS reader: Dan Pupius had posted a blog entry. The entry was a simple sentence that pointed to his post on the Gmail blog about code changes that were being rolled out. I had the pleasure of speaking with Dan way back when I interviewed with Google. I was impressed then, as he’s a really bright guy, and am even more impressed now.

Dan doesn’t blog very often, but when he does, it’s usually something important and/or extremely useful. This case is no different. The changes to Gmail are quite impressive; it feels to me that the app is moving about three times faster than before. The clicks are ultra-responsive now, as opposed to the familiar interaction delays I grew used to. Congratulations to Dan and the whole Gmail team, performance improvements like this don’t occur without a lot of work and attention to detail.
