Java and UseLargePages

We have a number large heap (6-12Gb, some larger) JVM servers. I'm considering configuring Linux for large page support. As usua开发者_如何学Pythonl YMMV, but for those of you that have availed yourselves of this capability, how much difference did it make for your situation? How important is the choice of page size specified in LargePageSizeInBytes?

Thanks,

I have collected a number of resources for large pages, for Java and other environments / applications / OSes / hardware (MySql, Linux, Sparc, AMD). Some people get very significant increases in performance. http://zzzoot.blogspot.com/2009/02/java-mysql-increased-performance-with.html [Note I last updated this page 2010/07]
