May be hostname resolution? As far as I understand the default resolver timeout is 5 seconds (man resolv.conf) - two failed name lookups gives you exactly 10 seconds. Try --skip-name-resolve on the remote mariadb server and make sure you only use IP adresses when granting privileges and when connecting to the server.
