Hey Chris -

That's surprising to me. I think that's the only example I've heard of
that. What tools did you use to compare the performance under the ORM
and without it? I've been researching making that comparison and I
haven't come up with a good set of tools. I'd love to get some advice
from you about this at some point. I'll keep an eye out for you on
IRC.

Thanks!
