I apologize if my level of institutional knowledge of these things is
lacking, but do you have any
benchmarking results between 0.22 and 0.20.2xx? The reason I'm asking
is twofold -- I really
would like to see an objective numbers qualifying the viability of
0.22 from the performance stand point,
but more importantly I would really like to include the benchmarking
code into Bigtop.

In terms of bugs -- same question. Is there any publicly available
list of, at least, the critical
ones that make 0.22 not viable from your point of view?

Thanks,
Roman.
