-------- Message original -------- http://asserttrue.blogspot.com/2008/11/why-64-bit-java-is-slow.html To get more heap than that means either moving to a 64-bit JVM or using Terracotta. The latter (if you haven't heard of it) is a shared-memory JVM clustering technology that essentially gives you unlimited heap space. Or should I say, heap space is limited only by the amount of disk space. Terracotta pages out to disk as necessary. A good explanation of how that works is given here. -- =================================================== Tina Odaka RIC - IDM - IFREMER Tel: +33 (0)2 98 22 41 85 Fax: +33 (0)2 98 22 45 46 email: Tina.Odaka@ifremer.fr http://www.ifremer.fr/pcim ================================================== -- Éric <chatellier@codelutin.com> Tel: 02 40 50 29 28 http://www.codelutin.com
