Mysql eats a lot of RAM?

[RedMonkey]

So, I have currently around 800ish players on the server.

When the map server tries to save info of every character and guild, Mysql is eating almost all the ram of my server.

Is this normal? BTW I have 4GB of rams..

depend on your database sizes, query statement, it affect the RAM usage too.

Hello Emistry, thank you for the reply. I was wondering if using another server as a host for my database would help me fix this? Out of ram makes the map server freeze. i am frustrated.

Why not upgrade?
