I’m at the O’Reilly Velocity Conference in San Francisco today and will be sitting on a panel with Bill Scott, Ernest Mueller, and Scott Ruthfield. Steve Souders is moderating.

Bill is kicking off the show with something really exciting — the Jiffy plugin for Firebug. Jiffy relies on Scott Ruthfield’s Jiffy-Web open source analysis suite to track the performance of an application from both the client and server side. Client side performance tracking is something I’ve been a fan of for a while (I used a similar technique for the Dojo Charts benchmark last year).

This looks like a great new tool to make this type of analysis more accessible, and I’ll be attending Bill’s sessions today to get more information.
