RE: Performance Issue :: CPU utilization reaching 25-30 %m for SSH_CONNECT if Server is OFF and SSH_OPTIONS_TIMEOUT is 30 seconds

["V Sidnal, Nagraju" <nagraju.sidnal@xxxxxxxxxxx>]

Hi All,

Please guide me on this. Whenever ssh_connect(session) is invoked , it is taking 12-25% of CPU.
Using LIBSSH 0.9.4 and windows version is 10.0.14393.0.

Regards,
Nagraju

Hi All,

Facing strange CPU issue when performing ssh_connect(session), with IP/Hostname which is OFF.  And SSH_OPTIONS_TIMEOUT is 30 seconds.
I see that is taking 25-30% CPU. Please suggest me is there any bug in 0.9.4 version of libssh, related to performance.
