I just added a new tool to the moriarty library for app speed analysis. I wrote this tool while working at Pulse, so the post is on the Pulse Eng blog. Check it out.
Some background: A few months ago I had the opportunity to contribute to the Pulse news reader app. This is a great app for reading news, blogs, facebook updates, and twitter in one place. Among other honors, the Pulse team just received an Apple design award at WWDC 2011 — these guys know what they’re doing. The particular tool being released allows you to easily get line-by-line, nanosecond-resolution timing data for your code. As usual, it’s an open source tool under the Apache 2 license. Here’s the post.
