I'd say, let your applications decide for you. Application compatibility (especially 3rd party) will be better on i386. But if you don't have any such issues x86_64 is the way to go. The 2nd thing to consider is memory addressing, this will be better on x86_64 (especially on your 4 GiB box). i386 will split your 2 or 4 GiB into low mem and high mem and that will be harder for applications to use than the flat model provided by x86_64. And in the end, if at all, consider possible performance differences... /Peter -- ------------------------------------------------------------ Peter Kjellström | National Supercomputer Centre | Sweden | http://www.nsc.liu.se -------------- next part -------------- A non-text attachment was scrubbed...
