32 vs 64 bit performance

[PJ6]

This is probably an old question but Google isn't giving me anything useful.
Can someone point me to any articles written on the performance differences
for .Net applications compiled for and running on 32 bit vs 64 bit systems?

Thanks,
Paul

I'm pretty sure if the specs for the system are the same, just that one
system is 64 bit versus 32 bit, that you won't see a difference. Where you
could see a difference is in a code where you require the large address size
and code using available memory rather than segmenting the problem to small
chunks of memory. That isn't a processor difference, but an algorithm
difference.

Well i couldn`t explain it but i noticed in the past that my 64 bit
capable app ( compile with the ALL flag win VS.Net 2003 ) running on a 64
bit operating system performed much bether

This was at that time on windows server 2003 X64 on a Acer 1524 WLMI ( AMD
X64 ) with 2 GB memory

So i guess the 64 bit framework did generate bether optimized code by the
way the project was a Business logic server wich implmeneted a .Net remoting
interface
that queryed a lot of data and in the end sended this to connected clients
through a TCP channel

In many cases 64-bit performance maybe in fact slower, since the CPU
needs to process larger blocks of data.

Nevertheless, there are advantages to using 64-bit such as larger
address space.

You'll probably squeeze more performance by optimizing your code and
making it multi-threading compatible, thus allowing you to take
advantage of multiple cores.
