The Ultimate Guide to High Availability with MariaDB

Restore Performance

Is it possible to restore a 32GB dmp file generated by mysqldump in less than 1 week? I am trying to estable a master/slave replicaiton schem with mariadb version 5.5.22. I generated a dmp with mysqldump (noting the log file and log position) and copied it to the slave machine. On the slave restored this file, but the restore took over 1 week to complete. This was using all of the performance tricks I could locate such as turning off foreign key and unique checks and adjusting various buffers.

The slave database being restored is running on a linux (CENTOS) VM with 8GB memory and 4 3.3GHz processors available. The mariadb version is 5.5.52. There are no other processes running on this VM other than the database.

This seems like an unacceptably slow restoration process. I have restored larger databases (non-mariadb) within hours, it seems mariadb would also be able to do this.
