Eclipse 3.1 Released 343

Posted by Zonk from the new-flavour-of-coffee dept.
Jeff Myers writes "Eclipse version 3.1 was just released and is available for download. There are quite a few new and noteworthy features added in this release - including full support for Java 5.0 and improved support for developing rich client applications based on the Eclipse platform." Update: 06/28 21:03 GMT by Z : Denis emailed to request we use mirrors, as they're already getting hammered pretty hard.

    Is Eclipse any faster than when they first released it.

    That was my only knock of the software. It would be so slow. William. Shatner. could. deliver. a. line. quicker.

    For those who don't need a full blown IDE, just something to write java in and compile, try textpad. It is lightning quick.

    But I bet with faster CPU's, eclipse is alright now. But it was so slow on a PIII 1ghz with 512 megs. So slow.

    • Is Eclipse any faster than when they first released it.

      Yes.
      The site is down at the moment so I don't have any links but I know they've done a lot of great work on performance, especially on linux, since 3.0. GUI operations are way faster and the whole app is way more responsive as a result.

      Is Eclipse any faster than when they first released it.

      Actually yes. Performance was a major focal point for 3.1. Now that all the platform plugins are using OSGI bundle manifests and are all packaged as JAR files, things are much faster. Just starting up Eclipse used to take forever but it's much faster now.
      • Is it faster on Linux now as well as Windows? SWT on Linux has always been a real dog, and I'm keen for it to get faster because (a) it's the only thing stopping me using it over Swing, and (b) I run Azureus, which is amazingly slow because of it.

        For a system with 2.5 gigs, I expect you have more RAM than it needs. How much does Eclipse use up when you start it?

        • How much does Eclipse use up when you start it? It of course depends on your projects, etc. but for me, I have 6 large projects nearly always open at the same time. I define "large" by 40+ packages, with 8-12 classes each, plus a hundred or more config and jsp/html files. With all of this "fired up" it uses ~110 MB of RAM, and is quite responsive on a crappy 1.7GHz Centrino processor.

        There has been an option of doing CVS in Eclipse using ext: and not extssh: for a long time. I've been doing it for more than a year. Extssh may be the default on some wizard though, but if you just add the repository location yourself, you can select 'ext:' and it works great.

    • I have recently switched over to Eclipse from XEmacs for all my Java development. It is quite a memory hog (not that XEmacs isn't) but I've found it to be faster in general than XEmacs.

      I've only used version 3 and it's quite fast. Admittedly I'm on a 3 GHz with 512 MB RAM. I've heard several people the same thing, so maybe 3.X is improved. Occasionally, it will stall for about 30 seconds but I've never had it crash.

      I've found that developing in eclipse is faster than writing and compiling, because it highlights errors as you type (like how word underlines spelling mistakes). Once I'm done editing, I know it compiles, although just clicking the "run" icon is all that's required. (You can get a list of errors and go through them one by one if you prefer.)

      I also find the development aids they have to be time-saving. For example, a ctrl-T will bring up a class hierarchy tree. Ctrl-E will pop up a list of all files opened where you can type in a filter (Action*.java). Ctrl-alt-H will show all the methods that call the method you'are currently editing. Not to mention the refactoring, debugger, views, etc.

      Of course, each editor/IDE has their strength and weaknesses, but I've been quite happy with eclipse. The only thing I miss is a GUI editor like netbeans has.
    • I found it faster, though I didn't time it. You're a little short on CPU, so you're going to get slow performance anyway, are probably just better off with a text editor to do the development.

      It's worth noting that starting Eclipse for the first time takes 3 or 4 times longer to start than subsequent times.
    • Eclipse eats a crazy amount of ram. With a project at work, I sit around 330 megs of memory used.
      • Eclipse eats as much as you give it. I think it defaults to 256 MB ram, and given the chance it will fill that with cached lists of classes, methods, and so on in order to speed up search and overview functions.

        Try starting it with -vmargs -Xmx128M

        • I already have it starting off at 256 and going up to 700 something. The projects I work on are too large to fit withing 128 megs. People in my group get out of memory errors sometimes with the max VM size at 512 megs.

      From TFSite:
      Eclipse.org is the website of the Eclipse Foundation.

      Eclipse is an open platform for tool integration built by an open community of tool providers. Operating under an open source paradigm, with a common public license that provides royalty free source code and world wide redistribution rights, the eclipse platform provides tool developers with ultimate flexibility and control over their software technology.

      Eclipse has formed an independent open eco-system around royalty-free technology and a universal platform for tools integration. Eclipse based tools give developers freedom of choice in a multi-language, multi-platform, multi-vendor environment. Eclipse provides a plug-in based framework that makes it easier to create, integrate and utilize software tools, saving time and money. By collaborating and exploiting core integration technology, tool producers can leverage platform reuse and concentrate on core competencies to create new development technology. The Eclipse Platform is written in the Java language and comes with extensive plug-in construction toolkits and examples. It has already been deployed on a range of development workstations including Linux, HP-UX, AIX, Solaris, QNX, Mac OS X and Windows based systems. A full description of the Eclipse community and white papers documenting the design and use of the Eclipse Platform are available at http://www.eclipse.org./ [www.eclipse.org]

      The Eclipse Foundation is a non-profit corporation formed to advance the creation, evolution, promotion, and support of the Eclipse Platform and to cultivate both an open source community and an ecosystem of complementary products, capabilities, and services.

      Seems simple enough to me. They're a non-profit market-speak-driven company that wants to be a cross-platform coding development environment company.

      My money is on market-speak winning. I mean, anyone that can write "independent open eco-system around royalty-free technology and a universal platform for tools integration" is much better suited to that than Java. Maybe marketing Java...
