Awhile back I posted a link to some good Java performance basics. Today at the office I saw an incredibly outdated JavaTM Performance Tuning and Java Optimization Tips from 1999 being circulated as a good read (that’s JDK 1.2!) and it made me cringe. I was inspired to dig up some Urban performance legends and then more Urban performance legends, revisited. A lot has changed in 10 years, and many things we used to lament over (think inlining source code) are far better left to the modern compiler.
