   `SUPERSET_WEBSERVER_TIMEOUT` is set to 120 seconds. 
   
   `gunicorn` timeout is set to 150 seconds.
   
   gunicorn \
           --bind  "0.0.0.0:8088" \
           --workers $((2 * $(getconf _NPROCESSORS_ONLN) + 1)) \
           -k gevent \
           --timeout 150 \
           --limit-request-line 0 \
           --limit-request-field_size 0 \
           --access-logfile '-' \
           --error-logfile '-' \
           superset:app
   
   I'm still getting random timeouts (15 secs, 22 secs,.). Here's the error we get in the browser as the connection gets dropped by the webserver.
   
   `POST superset/explore_json/?form_data=%7B%22slice_id%22%3A62%7D&force=true net::ERR_EMPTY_RESPONSE
   TypeError: Failed to fetch`
   
   Do we need any specific timeout setting in ngnix for the above `SUPERSET_WEBSERVER_TIMEOUT` and `gunicorn` timeout settings to work ?
