Detailed Description

Control the formatted I/O download buffer.

When using formatted I/O operations (typically operator>>(std::istream&...) this option controls the size of the in-memory buffer kept to satisfy any I/O requests.

Applications seeking optimal performance for downloads should avoid formatted I/O, and prefer using std::istream::read(). This option has no effect in that case.
