Hi list, Neil! I have a little question because I'v got some performance problem... Is the RAID5 do any type of headahead with the default config? It is possible to disable the readahead? (if it is.) Or just the io_sched do that on the disks? How can I disable the whole headahead on top of the RAID5 array? The RAID5 can do multiple small (<4kb) reads of disks for the multithreaded read requests? (chunk size is 32k) Thanks for helping!
