class DRb::DRbConn - drb: Ruby Standard Library Documentation

# class DRb::DRbConn

Class handling the connection between a `DRbObject` and the server the real object lives on.

This class maintains a pool of connections, to reduce the overhead of starting and closing down connections for each method call.

This class is used internally by `DRbObject`. The user does not normally need to deal with it directly.
