CPU spikes to 100% when using openSSH for windows

I am using openSSH for windows (OpenSSH 7.1p1-1). I noticed that after few days that the sshd.exe processes are at the range of 20% cpu the spike to 100% utilization all taken by the processes. i googled the issue and looked here and found one answer saying that when running openSSH along with an antivirus they can compete for resources, the thing is i do not have anti virus on this windows machine

Has anyone encountered this issue before?

If you're using Windows 10 you could try installing Windows's Official OpenSSH Client (and server too if you'd like remote access to Windows over SSH).

From Control Panel -> Apps, in Apps & Features tab, click on Manage Optional Features and add OpenSSH Client.

You might have to uninstall the other client, run ssh.exe using full path or adjust your %Path% to run the correct version. Once installed Windows's version of ssh.exe should be installed in %windir%\System32\OpenSSH\ with this directory added to your %Path%.
