in thread A better implementation of LCSS?

OK, I guess I'm clueless in the ways of benchmarking. Do you think the results in the String::LCSS_XS POD are bogus, too? Unfortunately, I don't have the code for that benchmark. Can someone point me to a way to generate a meaningful test?

    Memoize() is only of benefit if you call the memoised function multiple times with the same arguments -- ie. when it can return the previously returned value instead of recalculating it.

    Repeating the same test for a benchmark of a lcss() function makes for a totally artificial test.

    Of course, you could also apply the memoisation to the XS version and you'd restore the differential.
