SimpleJson is slow .... is there any C Compiled version ?

[sanket]

Hello All,

I have created an API which fetches some data from the database.
I am using simplejson to encode it and return it back.

Now the problem is that, this API is being called for millions of
times in a sequence.
I ran a profiler and saw that most of the time is consumed in encoding
my database results in to json.
So I was just wondering is there any C compiled version of simplejson
is available?
or any help regarding this issue would be appreciated.

Thank you,
Sanket
