Hello, The JBoss for Administrators course (RH336) mentions the following: Thread scalability is your most important concern Java applications are heavily threaded Burden on the OS is on the efficiency and scalability of thread scheduling Thread scalability on Linux has been an issue I'm wondering whether threading scalability on Linux is still a concern? Anybody know of any recent articles/discussions/stress test results on this topic involving JBoss (> 4.0.5 ), RHEL 5 and Sun JDK1.5 ??
