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)

mb_strrpos - Find position of last occurrence of a string in a string

SYNOPSIS
int mb_strrpos (string $haystack, string $needle, [int $offset], [string $encoding = mb_internal_encoding()]) DESCRIPTION
Performs a multibyte safe strrpos(3) operation based on the number of characters. $needle position is counted from the beginning of $haystack. First character's position is 0. Second character position is 1. PARAMETERS
o $haystack - The string being checked, for the last occurrence of $needle o $needle - The string to find in $haystack. o $offset - May be specified to begin searching an arbitrary number of characters into the string. Negative values will stop searching at an arbitrary point prior to the end of the string. o $encoding -The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used. RETURN VALUES
Returns the numeric position of the last occurrence of $needle in the $haystack string. If $needle is not found, it returns FALSE. CHANGELOG
+--------+---------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------+ | 5.2.0 | | | | | | | Added the optional parameter $offset. | | | | +--------+---------------------------------------+ NOTES
Note The $encoding parameter was moved from the third position to the fourth in PHP 5.2.0. For backward compatibility, $encoding can be specified as the third parameter, but doing so is deprecated and will be removed in the future. SEE ALSO
