Heh, so I really do like "efficiency", much more than performance or

But I really do think that we shouldn't try to bikeshed the name much. IMO,
while it's great to throw out ideas around better names, and certainly to
point out any serious *problems* with a name, but past that I'll be happy
with whatever the folks actually working on this pick.

I think we should all focus on the relevant technical discussion, and float
any name ideas that we have, and let Derek and Qin make the final call on
the name.
