Re: why MySql 8.0.17 Select query performance is slower than Mysql 5.7.26?

Retrieving all data of one table in one single thread might indeed be slower but I don't expect double the time. Do you have any workload difference ? Is this a test machine or your production machine ?

Is your table InnoDB and have you the same InnoDB settings ?
