I have a 2 node centos 6.5 Percona XtraDB Cluster cluster set up on Hyper-V 2012 r2 i also have a single mysql server set up on the same Hyper-V server using the same settings. I tested importing a 1.4m sql file, which is a backup of a sugarcrm database, and it took about 24 minutes to import, and 10 min to drop the db after import. On the mysql server it took about 2 min to import and 22 secs to drop. I know that replication hits on performance but i must be doing something wrong for it to be that bad. Any suggestions?
