infoq Sun Releases Java 6 Update 18 With Significant Performance Improvements and Windows 7 Support

久々に気合いが入っているアップデートだな。
特に目を見張るのがNUMA(Non Uniform Memory Access)アーキテクチャ上での最適化だろう。

あと、

    • More garbage collection improvements, including new default java heap configuration in client and server VMs.
    • Classloading optimisations for faster startup.
    • Application start-up changes include savings of around 100-200ms on systems where Direct 3D is used.
    • Concurrent download of jars for Web Start applications and applets.
    • A 20% reduction in the amount of time needed to create jar files.

この辺も地味に効く改善だ。

Sun頑張れ、超頑張れ。
