Re: benchmarking Flex practices

... it seems this patch needs attention, but I'm not sure from whom.
The tests don't pass whenever the server encoding is not UTF8, so I
suppose we should either have an alternate expected output file to
account for that, or the tests should be removed.  But anyway the code
needs to be reviewed.
