The innodb_flush_sync variable, which is enabled by default, causes the innodb_io_capacity setting to be ignored during bursts of I/O activity that occur at checkpoints. When configuring innodb_io_capacity_max, twice the innodb_io_capacity is often ... The InnoDB master thread and other threads perform various tasks in the background, most of which are I/O related, such as flushing dirty pages from the buffer pool and writing changes from the change buffer to the appropriate secondary ...
