innodb_flush_neighbors=ON should be ignored on SSD

    XMLWordPrintable

Details

    Description

      innodb_flush_neighbors was an optimization for rotating disk, to have larger IO size. It costs CPU, and it does not bring anything for the SSD. I think OFF is now a good default (and also it has good in the past couple of years)

      See for example
