Django-piston takes huge response time in read
Maybe you have defined the fields parameter to fetch many related objects(Objects with foreignkeys,onetoonekeys and manytomanyrelations to the object being fetched). This will slow down your response. Can you post your code?
When returning result from the read method, it takes a huge amount of time to generate/send response (for like 30,000 records with 6 columns, it takes around 14 seconds).

Is this fine and it normally takes this much time?
If this ins't fine, what can I do to reduce the time? What/Where could I refer to?

Any help?
