Does JDK 1.5 support hugepages on Linux
[213 byte] By [sadmara] at [2007-10-1 23:57:22] 
JRockit JVM has the facility by which it uses hugepages if available to store its heap within the Linux kernel. I am trying to find a similar facility within Sun's JDK 1.5. Any clues?Thanksrh
The JDK has had large page support on Solaris for many releases but it is relatively new on Linux. There are a few issues with some older kernels and the feature is disabled by default. The -XX:+UseLargePage option is used to enable it. To use this option you need to be using 5.0u5 (just released), or a mustang (Java SE 6.0) build.

Alan,Thanks for that information. I was able to download JDK 1.5.05 and have the JVM use hugepages.rh
