The command line for measuring filesystem read and write speeds was:

$ dd if=/tmp/diskmnt/filerd.zero of=/dev/null bs=1M count=1000 iflag=direct
$ dd if=/dev/zero of=/tmp/diskmnt/filewr.zero bs=1M count=1000 oflag=direct

Try testing with "fdatasync" instead of "direct" here.

Sorry, "conv=fdatasync" instead of "oflag=direct".
