How to handle parallel 100 "nova show" requests in Grizzly?

I have issued 100 parallel nova show requests, then i am getting Internal server error.

Below are the changes which i have tried to resolve the problem, but none of them worked.

In /etc/nova/api-paste-ini, i have added the below parameter

limits =(POST, "", ., 200, MINUTE);(POST, "/servers", ^/servers, 50, DAY);(PUT, "", ., 200, MINUTE);(GET, "changes-since", .changes-since., 400, MINUTE);(DELETE, "", .*, 200, MINUTE)

In /etc/nova/nova.conf

osapi_compute_workers=200

Is there any other configuration changes need to be set to handle parallel requests.
