HI Mr. ore,

Thank you for your bug report.

However, there are already 38 (thirty eight) bugs that report significant drop in performance in MySQL 8.0, compared with MySQL 5.7.

This is a very well known fact, that has been discussed in various forums already.

This is due to the fact that that 8.0 has introduced so many new features. Using those features, described in our Reference Manual, could improve the performance.

Not a bug.
