Did all necessary modifications according to Boost 7.x installation instructions but no much difference

Hi everybody,

I created a json view named company. The cck have more than 200 records(the count will increase).
Example

www.mysite.com/company

calling this web service gives me the json data. As i felt this is taking time(8 secs approx) to load json content i installed Boost module and configured accordingly to http://drupal.org/node/1459690.

.htaccess is also modified, No problem in my cms. Everythng seems to be working fine. But din't notice any change in the speed of josn views. I even came to know Boost module can load 3000 pages/sec but i have only 200(at present). It is still taking more time for loading . How can i make my json views to load faster.

Please help.. Wainting for a better solution since long time.
