No, because often they're paying them to work on fixing real bugs and adding real features, not simply plastering a bigger number on the box that means nothing. I could build our in-house developed software in 64-bit, but it would do nothing but make it take up more memory.
Even though the memory footprint increases, you get a good increase in performance. Not only that, but memory is a lot cheaper now than it was 10 years ago, so there is no reason to throttle our applications by keeping them 32-bit.

Under certain workloads and under certain conditions, not universally. As I already mentioned, our in-house software (at least the one I work on) would not benefit at all.

I just don't see why we have to have two separate API's in one OS. It's bloat. All of that can be reduced or eliminated completely to have a smaller installation footprint for the OS, and considering all apps would have to run at 64Bit, it would streamline downloads and even deployment in an enterprise environment, not to mention consumer. IMO, 32bit is a waste at this point.

You don't do software development, do you? Converting 32-bit applications to 64-bit requires regression testing and validation/certification. Depending on the size and complexity of the software, this is easily weeks to months of work. If it provides marginal benefit, why would a company choose to spend the time and money for the conversion?

That is absolutely not true. You do not get an increase in performance just from going to 64-bit. Most applications simply do not have intensive FP calculations to warrant the investment of conversion.

Why would you want memory footprint to increase? You must mean available memory... but most applications do not require more than 1-2GB. Why bother to migrate for marginal benefit.

In our case it would possibly require converting some legacy software to 64-bit as well (I'm not entirely sure as I don't know the extent of its function). "Legacy" in all senses of the word: Nobody knows how it works, nobody can read the code, and worst of all, no unit tests to know if all the memory leaks were intentional thumb.gif

I agree almost entirely. Operating Systems moving to 64 bit has obvious benefits - as there are some applications that require (or at least, are helped by) 64 bit addresses and true recognition of 4GB+ memory space, but for every application? Far better to let the developer choose which to use than to force them to use 64 bit programmes when it just acts to slow the programme down.


Take a word processor as an example. Will it ever need over 4GB of memory, or 64 bit addresses? Probably not. Similarly, an intensive spreadsheet *might* benefit from the FP increases.


However, I think that we're getting a little off topic here? We're supposed to be discussing ReFS (and the issues that surround it), not 64 bit vs. 32 bit computing?
