Re: point_lun is slow


I am using FibreChannel disks and found out that reading a sector
at a time feels like reading a floppy. With chunk sizes of 256K
I get about 7MB/sec sustained speed. So at least on the Fibre you
have to use large chunks to get any kind of performance.

I also tried 64K chunks but the performance was much worse.
