I went to compile rawio out of the ports, but a declaration needs to be changed and I havent had time to figure it out. (Alas, I am not a programmer) cc -O -pipe -g rawio.c -o rawio rawio.c: In function `dochild': rawio.c:496: incompatible types in initialization *** Error code 1 For now I have mostly been doing tests with bonnie and iozone testing out the various configurations and settings in RAID 0,1,3 and 5. Generally, as expected, the controller only really shows off when there are multiple things going on. e.g. two or more copies of bonnie running at the same time. I also have a Mylex 960 that I will test out next. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers could setup a national IP network."
