Need Help - Gatling request remain in waiting state.

Gatling request remain in waiting state.

Executing the load scenario setup with constantUsersPerSec(60) during (5 minutes)) but I see lots of requests are in waiting state.
After execution I observed in the report Req/sec is 5.88 and also Number of requests per second graph says same.

example -

[- ] 1%
waiting: 19795 / active: 1 / done:204
