Re: raw Vs kernel aio

You can (and should) use raw disk space whether you use kernel io or not. Using kernel io seems to give varying results - some claim performance gains while others say things slow down. This is something you'll have to try for yourself. You may also want to try the environment variable setting "IFMX_HPKAIO_VER=1" instead of "KAIOON=1". I don't know what this does exactly but it seems to give the best results. ---------------------------------------------------------------------- John H.
