Maybe amd64 could be described as 'tier 1.5' ;o) Can I ask for honest opinions here on what speed (or other?) benefits I should get by running amd64 over i386? I will never be using more than about 1 G of memory on this particular machine so memory limit is not an issue. Maybe I should just rebuild the machine as i386? It's an Athlon64 3400+ on a Gigabyte motherboard - used mainly for cross-compiling to Linux and mingw32, NFS file sharing, some X11 over the network with my local Mac OS X machine as X server and using my own C/C++ maths code (which must run as fast as possible).
