1000W Data:

ID is an indexed field, 8 bytes of bigint, and the database engine is MyISAM

Code as above

100 times, 1.2s, average per select 12ms

Conclusion:

Data volume engine average Time index field

100W MyISAM 0.1ms

100W InnoDB 0.1ms

200W InnoDB 4.5ms

500W InnoDB 5ms

1000W MyISAM 15ms (paralysis is incredibly slower than bigint)

1000W InnoDB 12ms (bigint)

1000W MyISAM 12ms (bigint)
