I have installed mysql 8.0.13. I started restoration of 20GB table in mysql and it took around 36 hours to restore.
When i tried to restore same table on mysql 5.6 it took around 5 hours only.
Mysql 8.0.13 is my master server and having 5 slaves attached to it.
When is do create table it took 4 seconds and while renaming same table it took 5 seconds.

mysql> select count(*) from tablename;

| count(*) |
| 82492459 |
1 row in set (4 min 7.53 sec)

For count of table also its taking more time.
