When managing low-traffic automation workloads in PowerShell 7.x, reducing the resource cost of repeated script execution is a primary goal. While utilizing runspace pools can mitigate the startup overhead associated with creating new sessions, there is a trade-off between memory persistence and execution latency.

The challenge lies in balancing the pool size to avoid exhaustion during bursts while ensuring that idle runspaces do not consume unnecessary host process memory during long periods of inactivity.

How does the default runspace pool behavior in PowerShell 7.x differ from Windows PowerShell 5.1 regarding memory reclamation?
What is the impact of pool size tuning on the total CPU cycle cost for scripts that execute intermittently?
