Well, actually, 64-bit mode has a small but measurable speed advantage, simply because the CPU has better architectural features (more registers, new instructions, etc) in the 64-bit mode. The speedup varies (and is sometimes negative) but people reported benchmarks from 20% faster to 20% slower, depending on the task: http://64-bit-computers.com/linux-ubuntu-610-64-bit-vs-32-bit-benchmark-test.html At the same time, 64-bit architecture is still 'new' as far as software is concerned: since the datatypes changed, we are through another 'not all the world is a VAX' transition, with software bugs and incompatibilities; e.g. AFAIK, Adobe still doesn't have a 64-bit flash player. So, I agree that 32-bit is the safe choice. This email is typed on a 32-bit Linux machine, but I am using a 64-bit Linux at work. ------------------------------------------------------------------------------ Gaining the trust of online customers is vital for the success of any company that requires sensitive data to be transmitted over the Web.
