Performance

Generating a host key is computationally intensive and can take up to several minutes depending on the load of the system. The system cannot accept any CLI inputs from that session while it is generating the key.

Encryption, data integrity validation, and compression are all computationally intensive. These features can affect router performance in the following ways:

• Reduce the effective baud rate compared with Telnet or the local CLI. Users are unlikely to notice this performance degradation because user interaction is inherently slow compared with other system operations.
• Increase the general load on the system CPU.
