Ed and Paul, Well I can only go by my experiences using Windows 2K3 64 bit over the last 3 months which certainly runs 64 bit applications considerably quicker than the equivalent 32 bit O/S. I think this is more to do with the fact that the memory address space is so much larger and the 64bit machine is running with 16Gb memory.
Appications tried are Arcserve, Doubletake and Virtuozzo (virtual PC) which is the main reason for going 64 bit in order to host 5 virtual servers. We have an equivalent Win 2K3 32 bit running the same software but this only has 4Gb and the performance is far superior on 64bit even allowing for increased processing power. In my opinion, memory is king here and the ability to address more than 4Gb of internal memory without paging in/out certainly provides faster performance even in 2K3 alone. Paul, as for the Motorola vs Intel debate, that is a no brainer. The Motorola instruction set wins every time. Having said that I most enjoyed using the Zilog Z8000 which had sixteen 16-bit registers. The register size and use were changeable on the fly. You could use them as sixteen 8-bit registers (only the first half were used like this), sixteen 16-bit registers, eight 32-bit registers, or four 64-bit registers including a 32-bit multiply and divide and all before 64bit chips were thought of. Coupled with a really fast and flexible instruction set it was a real programmers chip and the things you could do with the extended instruction set were mind blowing for the time. Happy days.

Is that right? I had heard, under some OSes, that 32-bit apps ran _faster_ under a 64-bit OS than they would in a native 32-bit. This isn't the same problem as 16-bit apps "thunking" when running in a 32-bit environment, I understand, although I haven't really paid all that much attention to the details. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com [excessive quoting removed by server] _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
