1) Exact selection: 4.1s
2) Wildcard selection: 5.0s
That is a difference. But it is also fair to say that for most
transformations, on a small dataset, it will be impossible to measure
a difference of any importance.
Well, the difference may not seem like much in the context of a single
tranformation but think about it in terms of a production system needing
to execute many transformations per second.
I've got a system which is running an average of 191 transformations
per second, and increasing the run-time by 22% in that situation would
be catastrophic for me.
