request is to slow with nginx, uwsgi, django, pgpool, postgresql
===

I have deployed service.
It served by nginx, uwsgi, django, pgpool, postgresql stack.

The page that have no db access is no problem.
However, the page have some data from fostgres is to slow.

actually, db query time is quite fast. under the 10 ms.

but result to client is over the 120000 ms
