Yes, you'll need a 64-bit machine in order to use over 2GB of JVM heap. You can set the maximum with -Xmx16g for example. Try that on a 32-bit machines, and you'll immediately get an error from JVM telling you to go get yourself a 64-bit box.

On the performace wiki page it mentions a test box with 16GB ram. Did anything special need to be done to use that much ram (with the OS or java)? Would Solr on a system with Linux x86_64 and Tomcat be able to use that much ram? (sorry, I don't know Java so I don't know if there are any limitations there). thanks, Kevin
