Title
Body
I'm currently working on creating an environment to test performance of an app; I'm testing with MySQL and InnoDB to find out which can serve us best. Within this environment, we'll automatically prepare the database (load existing dumps) and instrument our test tools. I'm preparing to test the same data dump with MySQL and InnoDB, but I'm already failing to bring the initial import to an usable speed for the InnoDB part. The initial dump took longer, but that didn't concerned me yet: $ for i in testdb_myisam testdb_innodb; do time mysqldump --extended-insert $i > $i.sql; done real 0m38.152s user 0m8.381s sys 0m2.612s real 1m16.665s user 0m6.600s sys 0m2.552s However, the import times were quite different: $ for i in testdb_myisam testdb_innodb; do time mysql $i < $i.sql; done real 2m52.821s user 0m10.505s sys 0m1.252s real 87m36.586s user 0m10.637s sys 0m1.208s After research I came over Changing tables from MyISAM to InnoDB make the system slow and then used set global innodb_flush_log_at_trx_commit=2 : $ time mysql testdb_innodb < testdb_innodb.sql real 64m8.348s user 0m10.533s sys 0m1.152s IMHO still shockingly slow. I've also disabled log_bin for these tests and here's a list of all mysql variables . Do I've to accept this long InnoDB times or can they be improved? I've full control over this MySQL server as it's purely for this test environment. I can apply special configurations only for initial import and change them back for applications tests so they better match production environments. Update: Given the feedback, I've dis
