GREAT! I haven't tested yet, just read your code.

Two remarks:
- will that work in terms of the expected result?:
t3lib_div::trimExplode(',', $testString, true, 3);
@see http://bugs.typo3.org/view.php?id=9779

- benchmark_trimExplode.php::trimExplode2()
the conditional should be 'if ($onlyNonEmptyValues){}' as
$removeEmptyValues is undefined.

Cheers,
Peter
