Why is mysqld process continuesly using 13.6% ram
I have setup 2 droplets, one is my database server. If I go to my website (which database is on my DB server), it continuesly shows 1 mysql process, using 13,6% mem. Only the CPU% usage goes up depending on the amount of queries. If i leave my website, the 13,6% mem usage stays.
Why is this happening, is it some kind of reserved memory? I mean, i am not querying at all but still it is using mem.
