The OpenJDK folk have more or less given up on traditional mark/sweep and even concurrent mark/sweep for JVM-based codes (most because there is still a need for a global stop the world collection at some points): the G1 algorithms that is now the default has a very different approach and appears to be a very significant improvement. See for example: http://www.infoq.com/articles/G1-One-Garbage-Collector-To-Rule-Them-All and all the Oracle and OpenJDK blurb. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
