Neither do I really. But it's the way CentOS/Debian/Ubuntu is going, so I'll learn to live with it.

I'm much more concerned with the future of running a lowend mysql server. Mariadb uses way more RAM no matter how you tune it, and MySQL Community Edition won't even start if innodb is disabled....

sman

Since when? What version?

skip-innodb

Doesn't work?

I sorted it out eventually. Something ocurred when mysql was started first with the default my.cnf settings (innodb enabled) and then restarted with a custom my.cnf (innodb disabled). Cleaning out /var/lib/mysql resolved it.

MySQL community version 5.5, CentOS 7:

[root@c7 ~]# pstree

Swap:           64M        1.4M         62M

That's with only a tiny bit of traffic
