Operating Systems AIX ISCSI poor performance 1.5MB/s fresh install AIX7.1 Post 302979395 by frenchy59 on Saturday 13th of August 2016 03:50:34 PM

I think I got my answer, I was simply dd if=/dev/hdiskX ... and I should have done dd if=/dev/rhdiskX ... using the raw device instead of the block device increased the instate result significantly !
Although on linux I was using the block device, I didn't get such difference with the raw device that's why it was confusing.

Thanks for your help guys.
