[docs] [issue12134] json.dump much slower than dumps

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

This is indeed the case. And the solution is obvious: call dumps() and then write() the result yourself. If dump() used _one_shot=True, it would defeat the purpose of minimizing memory consumption by not buffering the whole result.
