Hi jdseymour, thanks for your interest! It took me some days to login in ssh. Seems the port has been changed. Then I made what you have told me and applied the changes from the link you gave me. I did not notice any diference using the new values so I tried to change some of them and it got worst. I reverted it back to the values proposed and I let it be. Yesterday, a busy day, the server blocked for 15 minutes, load went above 20 with my 2 CPUS. I believe that was during backup or something. I will check today and tomorrow to see what happens. If it repeats I will have to use the my.cnf backup. I notice that there are some scripts to help tunning but I do not know or don´t want to risk install them.
