Configuring InnoDB for MySQL 5.6: innodb_io_capacity, innodb_lru_scan_depthPercona published Linkbench results. It looks like they set innodb_io_capacity to a large value but did not increase innodb_lru_scan_depth. I think that is a mistake. This is a mistake that I have made and that I hope you can avoid. innodb_io_capacity limits the number of pages flushed per second from the flush list. innodb_lru_scan_depth limits the number of pages flushed per second from the LRU
