Check my.cnf

Section titled “Check my.cnf”

Check that basedir and datadir in configuration file my.cnf are pointing to the correct directories. They can be muddled due to an old installation.

DNS lookups

Section titled “DNS lookups”

Disable DNS lookups as a faulty DNS server can cause slow connections as mysql reverse and forward looks up the IPs that are being connected. You can disable it using the —skip-name-resolve option.

Section titled “Use recommended settings”

Depending on the size of your server (memory, cpu, disk etc..), MySQL comes with recommended settings. Look into these instead of installing the defaults.
