Here they are:

The second image is the same results, but zoomed in. I could
bring the confidence intervals down by running this many times,
but each run takes 2h and I only have access to the
machine for a few hours at a time.
Those confidence intervals are generated from only 2 runs per benchmark,
which explains why they're so large.
