I am using this open-source script for creating RAID0 arrays in AWS EC2: [login to view URL]
I am having the issue which is indicated in the documentation, performance improvement is only 43% above single-volume EBS, far from the theoretical maximum 800% for an 8-volume array.
I need a fix to make the performance improvement at least 400% (half of the theoretical maximum) over single-volume EBS.
