Need inputs in improving performance

Hello Team,

Need to improve performance of my service.

We are calling a particular client using pub.client:http BIS by passing input arguments. One of the few input arg’s are maxKeepAliveConnections:2, keepAliveTimeout:6100 and newSession:no. What assistance I need is
minimize connection re-establishment than using the new connection so that I can get more performance of my service. Can see performance bottle-neck with above settings.

Thanks for your help.

We have used client http for many of our integrations and we use the default settings set at IS

Below is our setting, you can try with this if it helps.
