Lldpcli command program takes around 20 seconds to complete execution

Hi ,
To enable lldp I tried the below lldpcli command:
lldpcli configure lldp status rx-and-tx

This command takes 20 seconds to configure.
Is this expected ?
Also when I try a show command in parallel while doing lldpcli configure , it is also taking around 15 seconds.

Please confirm whether this is an expected behaviour.
