Apart from larger RAM, why > would these benefit from the 64bit world ? Or would they ? Any application that would benefit from being able to copy 64 bits at a time, i assume. Video applications and perhaps some encryption applications. Perhaps IPv6 core would have a slight benefit (although probably not with current code). Almost all the applications that you mention are doing mostly string operations (afaik). Perhaps VPN tunnels could benefit (unless of course you use hardware vpns like we do). -- Sten Daniel Sørsdal
