At the moment, there is no user configurable control over NetworkInterfaceASIO connection pools.

That is, there is way to change any of the following settings:

1. minimum pool size (current default is 1). A configurable min size parameter may help reduce the connection creation latency (useful for certain workloads).
2. max pool size (current default is unbounded / std::numeric_limits<size_t>::max()) .
3. host timeouts (currently default is 5 minutes).
4. refresh timeout (20 seconds) and requirement (60 seconds)

In any event, some user visible / configurable parameters may help.

Thanks,
