Hi all, I'm no MySQL DBA or expert, and learning to fine tune it futher on my 5 different VPSs. All of them are running MariaDB... 2 are v10.1 another 3 run v5.5. All running default configurations with no tinkering on the my.conf's or tuning.
I have been monitoring and (strangely enough) the MySQL Average load remains around 700 - 900Mb
Now I'm wondering, :
a 2GB OpenVZ VPS Running 4-5 avg visits+DB wordpress sites (MyISAM only) consumes 700MB
another 4GB KVMVPS with 2 CakePHP + 2 Core PHP sites (mix of inno+MyISAM) runs around 800MB
another 8GB KVM VPS with 2 CakePHP high visit site, with a 6 GB Database (mix of inno+MyISAM) and 100K pageviews also hovers around 850-900MB
I'm trying to detect the similarity behavior here.
Also can you educate me how to read the HTOP VIRT | RES and deduce actual memory consumption? how can I monitor which site/threads are consuming how much memory exactly.
I'm scheduled to do some MySQL tuning and cut down my costs for VPSs. I've seen people successfully running (with Caching) massive WP sites on 512mb VPS only. Just trying to hone my skills to achieve something similar.
