How to set pool size

Hey,
I wanted to know how can we explicitly set max pool size in `gocql`?

I mean changing the number of queries which will be run simultaneously.

We are having `150ms` avg response time in our monitoring in client side, but we are seeing `24ms` avg read latency in Cassansra exporter. Can it be related to pool size?

EDIT: I think that's the function in Java driver: `poolingOptions.setMaxRequestsPerConnection(num)`. What is the equivalent function in `gocql`?

Start by tracing gocql's session and connection-pool configuration and compare it with the Java driver's setMaxRequestsPerConnection. Confirm whether an existing Go setting controls concurrent queries per connection, then document its usage and explain whether it could account for the reported latency.
