And Ford could probably sell you two "exactly the same" Mustangs and one would be faster than the other - some machines work better than another would be my first point.

Second point - you state "almost equally patched" - so they are different - one of those patches may have made the OS utilize more/less memory, may have been quicker at releasing memory - and you can't tell if they are both in the same 'stage' of processing - maybe the amount of memory being used will be different (the other way around) at another time.

One may have more users conncected to the application that you are not seeing (especially if it's a Oracle/Sybase style app).

Each system is different - boot both at the same time and one may come up faster for no apparent reason.

The question you ask would be impossible to explain a 'reason' with the information provided - you are attempting to find a needle in a haystack.

Does the server with 'the problem' process the work in the time allowed? (if yes - stop worrying)

DESCRIPTION

       The following commands will return a true value (exit code of 0) if you are using an instruction set that the command name indicates.

       sun	  True if you are on a Sun system.

       iAPX286	  True if you are on a computer using an iAPX286 processor.

       i386	  True if you are on a computer using an iAPX386 processor.

       pdp11	   True if you are on a PDP-11/45tm or PDP-11/70tm.

       sparc	  True if you are on a computer using a SPARC-family processor.

       u3b	  True if you are on a 3B20 computer.

       u3b2	  True if you are on a 3B2 computer.

       u3b5	  True if you are on a 3B5 computer.

       u3b15	  True if you are on a 3B15 computer.
