I run 10 websites on a OVH Cloud VPS 2 (https://www.ovh.com/us/vps/vps-cloud.xml) xenforo is the website more active. I think that I have some problem with my db (mariadb). I can see it slow down on writes. HTOP say that I have often VDA busy 100%. Do you think that double up the RAM with OVH Cloud VPS 3 (4GB=>8GB) and change MariaDB configuration accordingly can give me a speed boost preventing this kind of slowdowns lowering the disk writes rate?
