Nginx module development practice with blocking call

[vivek goel]

I am writing nginx module which uses sqlite to do some read operation. As
sqlite read doesn't support non-blocking call(according to my knowledge).
What will be best solution to integrate it with nginx.
I am accepting near about 200 at the same time. One request takes near
about 200 ms to process. What method will be the best implementation using
nginx:


   1. Increasing nginx worker process count to 50-200. So I will having
   enough worker to accept client request.
   My concern it that will it increasing connecting time of a user on next
   request as there will be less chances that same user will be served by same
   nginx worker process.
   2. Doing te read in a thread and using nginx event based api to send
   response. So I can handle multiple client using only two or one worker
   process.
   3. Moving my code to fastcgi and using nginx fastcgi module to
   communicate with .

   What will be the best solution for this implementation ?
