I stopped bothering to respond to Nick Sabalausky, as obviously, he is not trying to discuss, he just throws his opinions around without any substance. As for startup time, who cares really, as you open it only once and leave it open afterwards ? As Jonathan and I have said now at least 3 times, you don't close it as it's your primary tool. And the reason it's slow is, at startup time, it loads: - the GUI toolkit SWT and the interface manager - the customized interface (called "perspective" in eclipse) - hundreds of plugins - the compiler - your open projects - all the files that were open last time As you may have noticed, almost all the tools that have their own non native GUI toolkit are slower to load. Any Gtk tool for instance. Even worse when you have plugins. Try to start the Gimp or Photoshop, and tell me if it's fast. And Emacs is slow to start as well. But who cares really ? They are not meant to be started 10 times a day. On my C2D, a fresh install of eclipse Indigo starts in about 12 seconds, with 340 plugins totaling 138 Mb in the plugins directory, most of them being actually loaded at startup time. Apart from that, eclipse happily handles projects with 2 million lines without a sweat on an average PC, so no, I don't think it's sluggish. If it *was* the sluggish chore Nick Sabalausky pretends it to be, eclipse wouldn't be chosen as the main platform by Zend, Adobe Flex, QNX, Altera, Aptana, etc for their own product, there wouldn't be more than 5 million downloads for each release of the Java platform only (i.e not counting all the said customisations for other languages), and Java users would instead flock to Netbeans or Idea, which both have their strengths and are free IDEs as well. Now Idea (also written in Java) has a reputation for being actually a bit snappier (at the cost of a much long startup time, however, because Idea constructs the code index before opening the project while eclipse does it in background) as well as having many more functionalities, but I personnally haven't had the urge to switch so far. Conclusion on this pretty boring subject: Eclipse being slow is about as old a rant as saying Java is slow.
