Good Morning, Over the weekend I was able to come up with a simple light weight cache that got me what I needed that was beyond a HashMap in simplicity yet the performance was in the nanosecond or picosecond range (0-999 picoseconds) I had a problem measuring the execution time since it had a tendancy to drop below a nanosecond using the System.nanoTime(). Got to go to my real job. -Tony View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967811#...
