Resolved Date: Apr 29, 2024
Found In Version: 10.22.33.13
Severity: Severe
Applicable for: Wind River Linux LTS 22
Component/s: Userspace
Upon debugging it was found that ssh-keygen is taking 3-4s to execute whereas in LTS19 it was hardly a second.
=====
PS: We ran set of tests on WR reference board and observed that "ssh-keygen" takes bit longer to execute in case of LTS22 when compared with LTS19.
