 Description   

Please measure performance impact of MDEV-16264 in IO heavy scenarios

branch : bb-10.5-wlad-MDEV-16264

Interesting setups

  • innodb_use_native_aio=1 + innodb_flush_method = O_DIRECT on filesystems that are libaio friendly, most interesting
  • default settings for innodb_use_native_aio,innodb_flush_method
  • innodb_use_native_aio = 0

Too late, it was critical until it was merged. I measured myself.
