Changing "  stuff  " to (' ' x 1000) . 'x' . (' ' x 1000) gives:

       Rate    r1    r3
r1   1849/s    --  -99%
r3 166166/s 8888%    --

It is important that a benchmark test what you think it is testing so what you think is being tested must entail a significant portion of the benchmark's processing time.

Update: BTW, my result for your original benchmark was:

       Rate   r1   r3
r1 767220/s   -- -10%
r3 855450/s  11%   --
