Hi please I need help I had someone install my sever configure and set up. The server is running very slow.
The server is running NGINX with virtualadmin control
He configured SSA for me which I do not feel comfortable with because he has root access.Can I delete the ssh he created and create another one.
Bottom line I do not want this person to have access to my servers what do I do. Also with the issue of slowness how do I fix it. My shared hosting plan else where are running faster than the VPS I feel he may have not configured it properly
Thanks

If all you want is to block him from the server, just do
sudo passwd <User>
To see what processes are slowing down your server, do
sudo apt-get install htop
and then
htop
You will be able to see which processes are taking up the most of your CPU and/or RAM.
