What I think would be nice to have, is a "high performance" option,
which would disable all logging everywhere in Swift, except for the
bare essential for Swift to be operational, in order to allow Swift to
get the best performance possible. This doesn't have to be the
default, but could allow a user to simply toggle a parameter and go
from fast performance mode to slow debug mode. I think what we are
trying to say with our recent experience with the BG/P is that we (as
the users of Swift on BG/P) would be willing to live with a boolean
error code if it meant that we could get significantly better
performance, which in turn would give us higher resource utilization.<br>

good != fast
for example, debuggable and non-desturctive-to-target-resource are other
desirable characteristics. the debuggable one is especially important.
Crippling the logging system to achieve faster execution is something that
should be turned on, not off - that moves error reporting back to a
boolean WRONG! style of reporting rather than the (I think) more useful
stuff that we have at the moment. Likewise, pushing stuff up to the limit
of what a site can handle (especially using GRAM2) is something that
should be approached with caution and not by default.
