Connect to multiple session very slow
Tried to connect for >10 sessions is very slow, beach ball cursor come up and the application goes not responding
I need to connect to ~80 devices at once

Hi moonb0w,

What version of SecureCRT is installed?

What is the specific Mac OS?

I have a suspicion as to the cause, it requires getting Trace Options output of a connections that is slow when connecting.

To enable trace options output:
  • First, open SecureCRT's main File pull-down menu and select Trace Options. If you open the File pull down menu again you should see a checkmark next to Trace Options, indicating that troubleshooting output is now enabled.
  • Next, connect to the remote machine. With trace options enabled, you will notice debugging information displayed in the terminal window that isn't normally there by default when SecureCRT is attempting to establish a connection, and at certain times throughout the lifetime of the connection.
  • Once the problem occurs, please right-click inside the terminal window and choose Select All, then right-click again and choose Copy to transfer the information to the clipboard.
  • Finally, open a text editor, paste the information from the clipboard into the editor program, and save it as a text file.
