Experiences from Building the Fastest OSGi Container on the Planet - Jaroslav Tulach
- 1. Netbinox The fastest OSGi Container on the Planet Jaroslav Tulach NetBeans Platform Architect
- 2. http://netbinox.apidesign.org Agenda • Being Fast!? • A bit of history • Demo • Technical details • Q/A
- 3. http://netbinox.apidesign.org Slow I/O During Startup Demo
- 4. http://netbinox.apidesign.org History 1 - Experiments • Sun and OSGi > Glassfish adopted OSGi in 2008 • Netigso > Friday project > Felix based > Parallel mode > Reuse of bundles • Glassfish in Nb > Middle of 2009 • Problem: How to get this into release? The Garage Days
- 5. http://netbinox.apidesign.org History 2 - Acquisition 18 months of despair • Sun collapsed in Spring 2009 > Acquired by Oracle > Approved in January 2010 > Czech Republic LEC on Sep 1, 2010 • JDeveloper > Primary IDE for Oracle Enterprise Technologies • Eclipse Foundation > Member and Contributor • Problem: Can NetBeans be useful for Oracle?
- 6. http://netbinox.apidesign.org History 3 - NetBeans 6.9 Theme • NetBeans Platform based on standards > Standard UI - Swing > Adopt OSGi as de-facto standard • OSGi interoperability > Reuse existing bundles > Use bundles on server/client side > Use NetBeans APIs in OSGi mode • Problem: > Is that enough to align with JDev? The public plan
- 7. http://netbinox.apidesign.org JDeveloper Going the same direction • JDev converted to OSGi meanwhile > Most of the work done > Big Bang rewrite > Using Equinox • Long term synergy vs. short term benefits > Reuse pieces of NetBeans in future > More speed right now • Netbinox on the rise > “Just” reuse NetBeans “startup caches”
- 9. http://netbinox.apidesign.org Caches & Speed Avoid I/O • 40% faster • Useful for desktop applications > Start speed is important > “Morning” launch • Intercept I/O queries > loadClass, getResource > File.exists() • Modular vs. monolithic apps > Deployment modular > Start is monolithic
- 10. http://netbinox.apidesign.org The Differences What is different in Netbinox? • 100% compatibility for bundles • Class and resource loading > ZipBundleFile replaced by JarBundleFile > Thread Context Class Loader • Equinox hooks > Registered slightly differently • OSGi APIs in Separate JARs > Shared by Felix & Equinox • Own Launcher > Configuration files use NetBeans format
- 11. http://netbinox.apidesign.org The Presence • NetBeans IDE 7.1 uses Netbinox > Mylyn + Bugzilla Connectors > Orbit bundles (JSCh, Apache) • JDeveloper on Netbinox > Other features than a speed • The common ground > OSGi as lingua franca > How do we share? With future outlook
