newrelic - Stack trace in New Relic shows 99% of time in Rails::Rack::Logger#call -


i've been working on improving performance of high throughput endpoint , i've reduced sql calls few ms average response time still > 150ms.

new relic highlights poor performing stack traces , in of examples see:

rails::rack::logger#call taking 99% of time (over 2 seconds). causing these hangups? there no logging happening , these entries don't show on average call endpoint?
