I discovered that my hard disk which can do 60mb/sec sequential read, under linux/lsilogic40909 fibre hba gives only 30mb/sec, 45 if I tweak a lot readahead (why I need to?). I have searched a lot in internet and it seems that: 1) fibrechannel howto was in sistina home page but now disappeared 2) fibrechannel specific mailing list for linux disappeared (archives to) Where can I search for help? Here it not seems appropriate to me. I have to find my bottleneck, please help with sending me docs. -- Mario Giammarco
