UnixBench results: Linode, Tilaa, Hetzner

· Linux

As announced in a previous post, here are the results of my UnixBench tests. I've been benchmarking VPSes from Linode (Xen virtualization) and Tilaa (KVM virtualization), along with a dedicated server from Hetzner.

Here are the details of each tested configuration:

Methodology and notes:

Here is the results summary:

Linode:  Debian (32-bit) - System Benchmarks Index Score            1011.4
Linode:  Debian (64-bit) - System Benchmarks Index Score            1000.6
Linode:  CentOS (32-bit) - System Benchmarks Index Score             920.9
Linode:  CentOS (64-bit) - System Benchmarks Index Score             912.3

Tilaa:   Debian (32-bit) - System Benchmarks Index Score            1127.3
Tilaa:   Debian (64-bit) - System Benchmarks Index Score            1244.0
Tilaa:   CentOS (32-bit) - System Benchmarks Index Score             766.6
Tilaa:   CentOS (64-bit) - System Benchmarks Index Score             767.8

Hetzner: Debian (32-bit) - System Benchmarks Index Score             736.4
Hetzner: Debian (64-bit) - System Benchmarks Index Score             818.3
Hetzner: CentOS (32-bit) - System Benchmarks Index Score             673.9
Hetzner: CentOS (64-bit) - System Benchmarks Index Score             623.6

Please note that these results should be taken cautiously, as they can vary in time (depending on host activity, more precisely disk I/O).

Some interesting facts to note however:

Detailed results (CPU information for each host, and full UnixBench output) can be found in the second part of the article.
