Mike Brunt has been writing web applications since 1993 and he's been using ColdFusion for almost as long. In the past, he's helped major companies such as AT&T and eBay with his ColdFusion expertise (he says eBay still uses CF internally to this day). Today, he works independently and specializes in tuning server side Java and CF applications.
Brunt shares his experiences and techniques in troubleshooting massive-traffic applications for large web properties. He's got plenty to say about the JVM and the changes taking place within the 64-bit computing space. Brunt gives some advice on how to use metrics on these low-level systems. Finally, Brunt emphasizes the importance of load testing. In his experience, less than 3% of CF applications get effectively load tested. You can find Mike Brunt's blog at www.cfwhisperer.com.
