While CentOS, Scientific Linux, and Oracle Linux Server are all derived from the same upstream source (Red Hat Enterprise Linux), how does the system performance compare between these RHEL derivatives? Here are some benchmarks of each of the 6.1 releases for Oracle Server, CentOS, and Scientific Linux, as they all do not perform the same.
After doing some Oracle Linux Server 6.1 testing over the weekend, I proceeded to install the recently released CentOS 6.1 and then Scientific Linux 6.1 to see how the performance of these Linux operating systems based upon Red Hat Enterprise Linux 6.1 compare in terms of performance. To some surprise, there are some noticeable performance differences in some tests.
