Hi,

I am testing pgbench with more than 100 connections.
also set max_connection in postgresql.conf more than 100.

Initially pgbench tries to scale nearby 150 but later it come down to 100 connections and stable there.

It this limitation of pgbench? or bug? or i am doing it wrong way?

---
I tested it with max_connection = 200 in postgresql.conf
and pgbench witn -c 180/190/200

Please reply.

Thanks and Regards,
Sachin Kotwal
