Multithreading issues

I notice that the default Visual C build of SDL specifies linkage with
the multithreaded DLL runtime C libs.

Does anyone know the performance implications of this?

In my current project, I’ve been steering away from the multithreaded
libs for performance fears (overhead of locking/unlocking resources).
I’m particularly paranoid about the speed hit that a thread-safe stl
would incur.

I do use threads, but I’m very careful with accessing shared objects
and make it a point not to use standard lib calls or (by implication)
stl from anywhere except the main app thread.
