Subject: Re: stdcxx stringstreams 2x slower than gcc
...
I think the difference between 8D and 12D is due to the mutex
in stingstream. Even though there's no locking the mutex still
is initialized and that's what I suspect accounts for the slow
runtimes. We need an issue to remind us to fix it as soon as
binary compatibility permits it.
I conclude from this that the mutex is exposed in the public ABI?
If so, why? I would think the mutex would not need be a part of
the public ABI.
You're right, it shouldn't be but, regretfully, it is. Hence
STDCXX-914: http://issues.apache.org/jira/browse/STDCXX-914
(With C++ templates it can be a challenge to avoid exposing
implementation details like this)
