Ajaxian talks to Steve Souders about YSlow, Firebug, and performance

Dion over at Ajaxian spent some time with Mr. Souders, Chief Performance Yahoo!, covering a range of topics:

• Most interestingly, the new version of YSlow, 0.8, optionally patches some misleading behavior in Firebug’s net panel regarding cached entries. This is Steve, so there’s one heck of a write up for the bug. The man is thorough.
  This is a good fix for Firebug, but my biggest pet peeve with the network panel is the incorrect start times for object requests. The start times reflect the point at which the DOM parser queues up a network resource to be requested, not the point at which the request is sent over the wire. The latter number is far more useful for optimization, but knowing Steve, YSlow 0.9 will fix that one too.
• Dion also sat down with Steve for a 6 minute chat and dropped it on Youtube. Hit the Ajaxian article to watch the video. It’s a great introduction to YSlow and the work Steve has been doing for the past 3 years.
• Finally, Dion has a great write up of Steve’s presentation from the Future of Web Apps.
