Re: MySql 5.7.3 m13 deadly slow - config issue?
Hi Øystein,
Your got it with the Collate, the Company table had COLLATE ascii_bin while the other didn't.
I added the collate to the temp_company table and the query took 3 seconds. Fabulous.
Out of interest - Why would an added collate stop two varchars using an index? (and why was this ok in an earlier Mysql version?)
