UnixBench

 

UnixBench has been around for a long time now, and it is a good general-purpose bench to test on Linux systems.

 

This is a system benchmark, and it shows the performance of single-threaded and multi-threaded tasks.

This shows the system indexes after a complete UnixBench run. Here, we get an idea of how much performance we gain using multi-threaded applications. However, many applications use single threads, so this number is really the base, and a higher clock speed will increase both indexes.

 

In UnixBench, we can see that the ASRock 2U12L6SC-2TS6 server is just a little faster than others.

 

SPEC CPU2006v1.2

 

SPEC CPU2006v1.2 measures compute intensive performance across the system using realistic benchmarks to rate real performance.

This benchmark has many different commands to use depending on what the user is looking for. For our tests, we used basic commands that run a full test.

 

Here, you can see the SPEC scores after full runs for Integer (int) and Floating Point (fp) tests.

Single core runs show how fast (speed) a CPU can perform a given task. In the multi-core runs, we set SPEC CPU2006v1.2 to use all threads, and this is a measure of the throughput of the system.

 

The additional cores/threads of this system has a huge impact on performance in these tests and really shows the amount of horsepower that a dual-socket system has over a single-socket board.

 

Single-threaded results are still very important, but when you need lots of those to run, moving to a dual-socket setup is the way to go.

 

The CPU2006 test is a long test taking up to two full days to run. We can see that the ASRock 2U12L6SC-2TS6 is able to go toe-to-toe with the server boards listed.

 

This test shows that the ASRock 2U12L6SC-2TS6 with a pair of E5-2697 V2 CPUs is a very powerful server.

Looking at the results of single-threaded integer runs, we can get an idea of speed at which the Intel Xeon E5-2697 V2s can crunch through the different integer tests. Not all CPUs are equal here, and ones that have a higher speed will generally perform these tests faster. In this case, this is the stock speed of the Intel Xeon E5-2697 V2s. Naturally, using an overclocked system or CPUs with a higher stock speed will generate higher results.

Now we run the test using all 48 threads of the dual-Intel Xeon E5-2697 V2 CPUs to measure the throughput of the system. In this test, more cores/threads will have a greater effect on the outcome.

 

We can see a big difference here using the dual-socket setup, with a three to four times performance boost being seen in many cases.

Just like the integer tests, we now run the floating-point tests in single (speed) mode. The lower clock speeds of the Intel Xeon E5-2697 V2s hold this bench back also.

Here, we see the results of the multi-threaded floating-point run that uses all 48 threads of the dual-Intel Xeon E5-2697 V2 CPUs. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
