I'm presenting again next month, at Usenix 09 in San Diego. I'm giving an all day workshop/tutorial on Tuesday June 16th. I have just updated my slides, combining the talks I have been developing over the years into Solaris/Linux Performance Tools and Tuning, which includes the Capacity Planning with Free Tools material that Mario Jauvin and I developed for CMG.
I have also posted the slides to http://www.slideshare.net/adrianco
Please come along, I look forward to seeing you in San Diego.
