In general for streaming i/o loads I think it is a good thing. dd as an example has an option to use O_DIRECT for the i/o. For a normal random i/o workload it is probably horrible.
I don't see O_DIRECT mentioned in the dd man page :-?
It's not, they call it "direct I/O". As in: iflag=direct oflag=direct You would have to use strace to verify that it causes the O_DIRECT flag to be passed to open, but I'm pretty sure.
