Dell EMC PowerEdge T140 Compute Performance
For this exercise, we are using our legacy Linux-Bench scripts which help us see cross-platform “least common denominator” results we have been using for years as well as several results from our updated Linux-Bench2 scripts. At this point, our benchmarking sessions take days to run and we are generating well over a thousand data points. We are also running workloads for software companies that want to see how their software works on the latest hardware. As a result, this is a small sample of the data we are collecting and can share publicly. Our position is always that we are happy to provide some free data but we also have services to let companies run their own workloads in our lab, such as with our DemoEval service. What we do provide is an extremely controlled environment where we know every step is exactly the same and each run is done in a real-world data center, not a test bench.
We are going to show off a few results, and highlight a number of interesting data points in this article.
Python Linux 4.4.2 Kernel Compile Benchmark
This is one of the most requested benchmarks for STH over the past few years. The task was simple, we have a standard configuration file, the Linux 4.4.2 kernel from kernel.org, and make the standard auto-generated configuration utilizing every thread in the system. We are expressing results in terms of compiles per hour to make the results easier to read:
Key here is that the big performance value driver is the core count and thread count. That produces a step function of performance.
c-ray 1.1 Performance
We have been using c-ray for our performance testing for years now. It is a ray tracing benchmark that is extremely popular to show differences in processors under multi-threaded workloads. We are going to use our 8K results which work well at this end of the performance spectrum.
If you are looking for a low cost 1-4 hard drive storage system, the Intel Core i3-8100 is a great pick.
7-zip Compression Performance
7-zip is a widely used compression/ decompression program that works cross-platform. We started using the program during our early days with Windows testing. It is now part of Linux-Bench.
Compression is a major performance component in the class of systems like the Dell EMC PowerEdge T140. Here the more cores, threads, and higher clock speeds you have, the better compression scales.
Sysbench CPU test
Sysbench is another one of those widely used Linux benchmarks. We specifically are using the CPU test, not the OLTP test that we use for some storage testing.
While we are showing differences between SKUs in terms of CPU performance, another aspect includes integrated GPUs. Both Intel Xeon E-21xxG parts and the Intel Core i3-8000 series parts have integrated GPUs.
OpenSSL is widely used to secure communications between servers. This is an important protocol in many server stacks. We first look at our sign tests:
Here are the verify results:
OpenSSL is a foundational technology for the web and many servers like the Dell EMC PowerEdge T140 will act as local web application servers. If you were to compare the Intel Xeon E-2136 to the Xeon E-2174G the former is less expensive but considerably faster due to having more cores. The Intel naming conventions are not necessarily in numerical performance order.
UnixBench Dhrystone 2 and Whetstone Benchmarks
Some of the longest-running tests at STH are the venerable UnixBench 5.1.3 Dhrystone 2 and Whetstone results. They are certainly aging, however, we constantly get requests for them, and many angry notes when we leave them out. UnixBench is widely used so we are including it in this data set. Here are the Dhrystone 2 results:
Here are the whetstone results:
Single threaded performance on all of these parts is significantly better than some of the lower power options. If you look at the AMD Opteron X3421 powered HPE ProLiant MicroServer Gen10, for example, the inexpensive CPU options in the Dell EMC PowerEdge T140 handily beat that solution.
Chess is an interesting use case since it has almost unlimited complexity. Over the years, we have received a number of requests to bring back chess benchmarking. We have been profiling systems and are ready to start sharing results:
Each frequency step up on different SKUs is accompanied by increased performance. We urge our readers to take the performance data we have and compare it to the incremental pricing in the configurator to make their purchasing decision.
Next, we are going to look at the Dell EMC PowerEdge T140 power consumption before finishing off with the STH Server Spider, and our final words.
