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)

STRRIPOS(3)								 1							       STRRIPOS(3)

strripos - Find the position of the last occurrence of a case-insensitive substring in a string

SYNOPSIS
int strripos (string $haystack, string $needle, [int $offset]) DESCRIPTION
Find the numeric position of the last occurrence of $needle in the $haystack string. Unlike the strrpos(3), strripos(3) is case-insensitive. PARAMETERS
o $haystack - The string to search in. o $needle - If $needle is not a string, it is converted to an integer and applied as the ordinal value of a character. o $offset - If specified, search will start this number of characters counted from the beginning of the string. If the value is negative, search will instead start from that many characters from the end of the string, searching backwards. RETURN VALUES
Returns the position where the needle exists relative to the beginnning of the $haystack string (independent of search direction or off- set). Also note that string positions start at 0, and not 1. Returns FALSE if the needle was not found. Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. EXAMPLES
Example #1 A simple strripos(3) example <?php $haystack = 'ababcd'; $needle = 'aB'; $pos = strripos($haystack, $needle); if ($pos === false) { echo "Sorry, we did not find ($needle) in ($haystack)"; } else { echo "Congratulations! "; echo "We found the last ($needle) in ($haystack) at position ($pos)"; } ?> The above example will output: Congratulations! We found the last (aB) in (ababcd) at position (2) SEE ALSO
