Ideally when Vusers are ramping up, hits/sec should also be increased linearly with Vusers. At certain stage during ramp up if you observe a saturation in hits/sec even Vusers increasing, this would mean the application is not able to process further requests from client. We usually call this as "Bottleneck" in the application. Normally at this stage clients start receving errors like 500 Internal, Connection Refused (no more connections allowed).

So, to figure out bottlenecks in the application it would be better to merge Vusers - Hits/Sec graphs and observed the trend of hits during the run.
