ls restrictions - 64 bit vs. 32 bit OS?

[aixmurderer]

I was wondering if AIX 5.1 (64 bit) has the same limitations we are experiencing with for example "ls *.txt" when there are more than 2048 files in a directory.

We are looking into buying p-Series boxes with AIX 5.1, should we go for 64 bit or 32 bit installations?

Anything else we should be wary of going to 64 bit when replacing our existing 43P's? What advantages does 64 bit offer? What pitfalls are lying in our way?

Any advice greatly appreciated.

32-bit and 64-bit performance comparisons

To examine the benefits and drawbacks of going from 32-bit to 64-bit mode
and further effects on the system,consult the following, AIX 64-bit Performance
in Focus, which is available at IBM Redbooks.

In most cases, running 32-bit applications on 64-bit hardware is not
a problem, because 64-bit hardware can run both 64-bit and 32-bit
software. However, 32-bit hardware cannot run 64-bit software. To find
out if any performance issues exist for applications that are running
on the system, such as Lotus Notes and Oracle, refer to
those application's user guides for their recommended running
environment.
