Lenovo ThinkServer RD340 Server Review

UnixBench has been around for a long time now, and it is a good general-purpose bench to test 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 of a performance gain we get 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.

Now we are seeing that the 2470 v2s in the RD340 come very close to other systems we have tested. This is starting to look very good for the RD340.


SPEC CPU2006v1.2


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


In our testing with SPEC CPU2006, we use the basic commands to run these tests.

Runspec –tune-base –config=tweaktown.cfg then int or fp

To do multi-threaded we add in –rate=40.


When SPEC CPU first came out, these tests could take up to a week to run, but as computers became faster, the test period shortened.


The user can do many things to affect the results of CPU2006 runs, such as compiler optimizations, add-ons like Smartheap, and different commands used to start the tests.




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 have a huge impact on performance in these tests and really show 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.




Looking at the results of single-threaded integer runs, we can get an idea of the speed at which the Intel Xeon E5-2470 v2s can crunch through the different integer tests. Not all CPUs are equal here, and ones that have a higher speed will perform these tests faster. In this case, this is the stock speed of the Intel Xeon E5-2470 v2s. Naturally, using an overclocked system or CPUs with a higher stock speed will generate higher results.




Now we run the test using all 40 threads of the Intel Xeon E5-2470 v2s 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, and a three to four times performance boost is 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 E5-2470 v2s hold this bench back also.




Here we see the results of the multi-threaded floating-point run that uses all 40 threads of the Intel Xeon E5-2470 v2s. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
