Disk IO and throughput benchmarks on Amazon’s EC2
http://stu.mp/2009/12/disk-io-and-throughput-benchmarks-on-amazons-ec2.html
We’ve been ironing out kinks in our production environment for the last few weeks and one of the things that worried me was if these assertions were true. So, I set out to run a fairly comprehensive test of Disk IO and throughput. I ran hdparm -t, bonnie++, and iozone against ephemeral drives in various configurations along with EBS volumes in various configurations.
For all of my tests I tested the regular ephemeral drives as they were installed (”Normal”), LVM in a JBOD setup (”LVM”), the two ephemeral drives in a software RAID0 setup (”RAID0″), a single 100GB EBS volume (”EBS”), and two 100GB EBS volumes in a software RAID0 setup (”EBS RAID0″). All of the tests were ran on large instances (m1.large). All tests were ran using the XFS file system.
