As promised here is the recording of the Sitecore Performance Webinar:

Also since the resolution of the video isn’t high enough to see the code I’ve also included a Sitecore package containing all the code samples I used during the presentation which you can download here.

I really hope this is of use to everyone, feel free to post any questions or suggest additions that could have been made to the webinar.
