"Does Red Hat Enterprise Linux perform any better (or worse)
than the various "Enterprise Linux" distributions that are derived
from RHEL? Now that Scientific Linux 6.2 was released, here is a
performance comparison of Red Hat Enterprise Linux, Oracle Linux,
CentOS, and Scientific Linux across three different systems.
Using the x86_64 6.2 releases of Red Hat Enterprise Linux,
Oracle Linux, CentOS, and Scientific Linux a set of benchmarks were
ran across all four enterprise-class Linux distributions on three
distinct systems. While all four distributions are derived from the
same upstream base (RHEL 6.2), this testing is seeking out a common
question of whether Red Hat Enterprise Linux or others have any
significant performance benefit. Of course, all of the testing is
being done in the stock configuration on each platform with the
stock packages, which are all effectively the same.
