VPS became very slow, at turtle speed!

:roll: Hi,

Recently my VPS has became very slow, almost crawling at turtle speed.
Here's the system info:

From what I see, it seems like mysql is using a lot of resources.
I've attached output of getinfo.sh for more info.

Any idea what's wrong and what to do?
Thanks in advance

Recently my VPS has became very slow, almost crawling at turtle speed.
I don't know what this means, in what way is the system slow? Is it slow return database queries? So responding to input at the command line? What is wrong?
1750 mysql 2.87 GB /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --log-e ...
It is not unusual for a database to grab as much memory as it can!
1750 mysql 122 % /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --log-e ...
Hmm, your database seems a little busy.

So back again to the question, what is wrong?
