[docs] [issue12775] immense performance problems related to the garbage collector

[Ezio Melotti]

Ezio Melotti <ezio.melotti at gmail.com> added the comment:

IIRC the C acceleration for json were added in 2.7/3.2, and are used automatically when you import json.  In the previous releases the json module was implemented in pure Python.  That explains why it's much slower on Python 2.5/6.
