Tuning the JVM is no fun, but tuning by repeatedly rewriting your own code is a lot more effort and risk. As for package size, there are people who bundle a stripped down JVM with a single app, but I don’t think that’s a good use of time—I’d much rather declare a dependency on the complete OpenJDK, and rely on the system package manager to install exactly one copy of it for all apps to use.
