Good example, but we have heaps of command-line utilities written in Java. Many complaints but never about performance or start-up time. For some low-level programs executed hundreds of time per session (like "ls") I agree it adds up and might cause frustration. Java is a bad choice for this niche, but you are not going to write them in Python anyway, aren't you? PS: Just tested "LS" in Java, less than a second run, I could personally live with that.
