Velocity is the O'Reilly conference dedicated to web performance.  The sessions focus on building web applications that are fast, scalable, efficient and available.  The next Velocity conference is scheduled for June 22-24 2009 at The Fairmont in San Jose, California.  Looking over the presentations from last years conference it looks like a great event which I hope to attend this year - what could be better than spending 3 days with others that are passionate about acceleration and application performance. 

Velocity is currently accepting proposals for presentations.  Check out Jesse Robbins' blog for a list of topics the organizers are interested in for the 2009 conference.
