Moving to InnoDb will be huge task for now... but from our analysis Mysql 8 performance is slow when the data is more and more.

Below is the comparison, between mysql 8x and 5.7. Time taken for same query in minutes,

1 Million 3 Million 5 Million 8 Million


Mysql 8x(min) 2.5 10.674 35.38 34.54
Mysql 5.7(min) 2.674 8.028 6.924 9.42


One more thing i want to understand is MyISAM performance got degraded in 8.X ?
