Re: Time taken for starting AMRMClientAsync

Vinod,

  Do you expect managed AMs also not take as much time as a second? Or as
Alejandro was saying, only unmanaged AMs?

  I think I am using managed AMs. If managed AMs also are not expected to
take that much time, I shall raise a ticket.

Thanks,
Kishore
