Performance improvement by using ctypes

[sly8787]

Hi,
I had the idea to integrate ctypes/Structure. I imagined that somehow:

1. Get the meta data of the collection (field -> type)
2. Build a object template by mongodb -> ctypes mapping definition
3. Use the ctypes object template to construct the objects

I've already started my own experiment and I have to say that the performance gain is enormous:

class Attribute(Frame):
    __metaclass__ = ctypes.Structure
    _collection = 'system_attribute'
    _fields = {
        'key',
        'label',
        'description',
        'metadata',
        'field_class',
        'multivalue',
        'tags',
    }

    _fields_ = [
        ('key', ctypes.c_char),
        ('label', ctypes.c_char),
        ('description', ctypes.c_char),
        ('field_class', ctypes.c_char),
        ('multivalue', ctypes.c_bool),
        ('tags', ctypes.Union),
    ]

Let me know what you think

Hi @TheGent sorry I haven't gotten around to replying yet, I am still intending to review your example, I'm very interested in the performance improvements you mentioned. Is there a reason you've closed the issue?
