Last year I published extensive benchmarks of Amazon's EC2 Compute Cloud but now with Ubuntu 12.04 LTS being available, here are new benchmarks highlighting Amazon's public cloud computing platform using all of the major instance types.
In this article are benchmarks of the major Amazon EC2 instance types when all of them were running Ubuntu 12.04 LTS with the Linux 3.2 kernel, GCC 4.6, and an EXT4 file-system. The instance types benchmarks included:
m1.small: 1 EC2 Compute Unit, 1.7GB RAM, 160GB instance storage, moderate I/O performance
c1.medium: 5 EC2 Compute Units, 1.7GB RAM, 350GB instance storage, moderate I/O performance
m1.medium: 2 EC2 Compute Units, 3.75GB RAM, 410GB instance storage, moderate I/O performance
m1.large: 4 EC2 Compute Units, 7.5GB RAM, 850GB instance storage, high I/O performance
m1.xlarge: 8 EC2 Compute Units, 15GB RAM, 1690GB instance storage, high I/O performance
m2.2xlarge: 13 EC2 Compute Units, 34.2GB RAM, 850GB instance storage, high I/O performance
c1.xlarge: 20 EC2 Compute Units, 7GB RAM, 1690GB instance storage, high I/O performance
These different Amazon EC2 instances were benchmarked using Phoronix Test Suite 4.0-Suldal. The numbers are pretty much as expected and align to the EC2 Compute Units with the numbers serving for reference should you be interested in Amazon's cloud and you can also compare your own cloud or other computer hardware to these results with OpenBenchmarking.org by running phoronix-test-suite benchmark 1207183-SU-EC2AMAZON49.
