Optimizing application performance is a multi-facet undertaking. Among
all the tools and methods available to us, getting a glimpse at
performance metrics from the processor point of view allows us to
highlight yet another facet of the application. Most modern
microprocessors include so-called performance counters that provide
event based drill-down of the processor utilisation and efficiency...[Read More]

Wang Yu from Sun ISV-Engineering published a great article named "Scaling your Java EE Application" which explains the fundamentals to create scaling Web applications with Java. The article describes the fundamentals which need to be applied after scalability bottle necks have been identified with jstack or the more comfortable Netbeans profiler. An excellent reading for everyone who wants to make a web application ready for the next generation of Chip-Multi-Threading (CMT) systems like the T2.
The article nicely complements the performance oriented work of ISV-Engineering which helps identifying and removing bottle necks on the system side. Wang Yu's article explains how to scale the application once the system bottle necks have been removed.
The second part of the ZFS hands on tutorial shows how to build mirrors and spare disks with the help of 6 USB sticks and a hub. It'll allow to test failure and recovery procedures with least cost components.[Read More]
