I have a small setup of MySQL Community Server version 5.6 running on KVM based VPS. 4 CPU cores are available and total memory is limited to 1GB. I use MyISAM tables mainly for Wordpress and few other personal projects.
Which server can best suit my requirements among MySQL Community Server(all 5.x versions), Percona and MariaDB? I am basically looking for better performance (mainly read) and resource utilization.
