Dumping ordered_json takes a very long time compared to json

[psiddire]

I've used ordered_json's for maintaining the order of insertion into the JSON.
I'm dealing with JSONs which are huge. Over 100000 lines.
It takes 100x more time to dump ordered_json compared to json.
Is there a fix planned for this? Any workaround (apart from moving back to json :) )

Debug mode?

I've narrowed down where the main issue is coming from.
I've the following line which is taking the most time.
Once the json is filled with data, I've
json_name.dump()

Is this function not optimized for ordered_json? Any alternative?
