[Discuss] Python programming questtion

[Jerry Feldman]

Thanks Rich. The issue is really paramiko. It is inherently not threadsafe.
But, there is a ThreadPoolExecutor module recommended by paramiko.

The job I am doing is:
Log in to remote host
Read a directory of student used IDs
Then use getent to get their full names.
This is mostly io bound.

I'll see where the thread pool executor takes me.
