When I write command-line programs, the JVM seems just fine. Even the startup time is not bad. However, when I compare actual editors and IDEs, JVM-based editors feel as painful as pulling teeth. Compare jEdit and Kate, or even Sublime Text. Or compare Eclipse, IntelliJ, Netbeans, etc. with any native app. Sure, these IDEs do a lot, but when I'm editing some UML diagram in Eclipse, for example, just clicking on an element to see its properties takes a few seconds. Seems like Eclipse is using all its libraries to accomplish this. I'm not running these on netbooks. I am comparing speeds across fairly well-endowed laptops and desktops. Maybe the fault lies not with JVM, but with the rest of the Java ecosystem.
