* wsrep_slave_thread is between 3 or 4 times number of CPU core.
* gcs.limit should be equal to wsrep_slave_threads * 5
* gcs.fc_factor should be equal to 0.8
* Flow control fraction should be lower than 0.02 (wsrep_flow_control_paused < 0.02)
* wsrep_last_commited committed level must be identical in all nodes
* Look for tables without primary keys
* Look for non InnoDB tables for Galera
