Yes, there can be a huge performance boost in some cases. When benchmarking my Protocol Buffers implementation, I was comparing it against the Java implementation – and I was really pleased, until I switched on -server… and saw the Java performance double. I don’t know the details of everything it does, but basically it lets the JIT work harder, as it expects the code to be running for longer.
I wouldn’t expect that to be the case in every application of course, but it can make a big difference. Of course, it won’t have much effect unless your application is already CPU-bound on the JVM. I have no experience with Oracle UCM, so couldn’t say how much effect it will have on your specific use. Have you already performed appropriate analysis of where the bottleneck in your system is?
