[Mono-list] Performance of Mono 2.10 vs. Mono 3.0

[Charles Esterbrook]

In preparing the report, I discovered that the regression is actually
going from 2.10.9 to 2.10.10, with no improvement in 3.0.3. Hopefully
that makes it easier to track down, though quite a bit must have been
done for 2.10.10. The installer package goes from 85MB to 102MB.
