Re: MySQL 8 - terrible performance
Hi Hans,
We still have to take a look at the mysqlslap results you provided.
However, meanwhile, I'd like to share some info I received from our development team regarding initialization and mysql_upgrade process. I think you will also find them interesting.
So like I already wrote it, we have added a lot of spatial references. Many inserts are then run in a single transaction during --initialize btu mysql_upgrade is restricted to statements that can be run by the user, and those tables can only be modified by CREATE SPATIAL REFERENCE SYSTEM. And each CREATE statement is a separate transaction.
When you run mysql_upgrade --force (not required after initialize ofc), you then run all these one by one.
lefred.
