Rackspace Cloud, or Amazon EC2, which is best? This is just a quick performance comparison using SysBench. The following products where tested.
| Product | CPU | Memory | Disk | Price |
| EC2 Small Instance | 1 virtual core | 1,7GB | 160GB | $0.085 per hour |
| Rackspace 256MB | 4 virtual cores | 256MB | 10GB | $0.015 per hour |
| Rackspace 1024MB | 4 virtual cores | 1GB | 40GB | $0.065 per hour |
Servers where running Ubuntu 9.10 i386, tests where performed on two different occasions, average scores where used. Here’s the results, less is good.
| Product | SysBench CPU | Sysbench Memory | Sysbench File I/O |
| EC2 Small Instance | 29.7s | 491.3s | 28.6s |
| Rackspace 256MB | 5.6s | 219.1s | 26.4s |
| Rackspace 1024MB | 4.1s | 196.1s | 17.8s |
The following commands where used to do the benching, interesting values was the total time to run the test.
sysbench --num-threads=4 --test=cpu run sysbench --num-threads=4 --test=memory run sysbench --num-threads=4 --test=fileio --file-test-mode=rndrw prepare sysbench --num-threads=4 --test=fileio --file-test-mode=rndrw run
Conclusion
According to SysBench, Rackspace Cloud is much faster then EC2 in general, and cheaper as well. EC2 however comes with more memory and disk.
