Wow. First off, I'm a die hard HP Proliant loyalist. When I investigated all 64-bit CPU's for a replacement to our sparc platforms, I found the same performance gulf between the Itainium and Opteron. I could not ignore the price/performance and we placed orders for several (non-proliant) servers. I cheered when HP announced their Proliant Opterons! As for Java, Version 1.4 is only available in the 32-bit flavor for Linux x86. The 1.5 beta for AMD64 is available from sun's site and is native 64-bit. (thus no 4GB memory stack limits per process) Please someone correct me if I'm wrong, but I think that if you run your bash envirmonment in a linux32 --4gb , that each of your 32-bit 1.4 java processes will have a 4GB user space to play with each.
