I'm currently moving a joomla website from a shared host to a dedicated one.
The problem I'm facing it's that I'm experiencing slow page loading and I think it has something to do with mysql. I tell you because sometimes (3 times since yesterday :S) mysql daemon goes down and I have to put it online again (log in /var/log/mysql/ doesn't report anything. Don't know why).
I turned on slow querys log and it reports this:

Do you think it's normal to have this times with this server?

Here's my.cnf file:

Hope someone can give me a hand with this. Thanks.
