When executing source select.sql normally, you will get that the empty set takes about 0.002s.
But when SET GLOBAL innodb_buffer_pool_size = 9223372036854775807; this value is the legal maximum value described in the document, and the execution time of source select.sql can reach about 50 seconds.
Performance drops greatly. Why is this?
