Consider that the scsi controller in an Indy gets about 2mb/sec throughput MAX (on a good day). Also, Indys don't support a large enough memory configuration that 64-bit would be worth it anyhow. What you would *really* want on such a machine would be n32 userland. You get full 64-bit instructions, but the binaries aren't huge. Steve
