Performance steadily when moving from 4 threads to 16 threads, while optimizing In addition, tuning the Red Hat Enterprise Linux 6 system increased
As Figure 3 shows, Red HatĮnterprise Linux 6 outperformed Windows Server 2012 when using all 16 physical cores Shows how a system performs under an extreme load. Test the floating point performance of the platforms out-of -box and optimized, which Performance systems that need to do heavy work. Measuring floating point computing power assesses the performance of high. Out-of-box Optimized Out-of-box OptimizedĪ Principled Technologies test report 3Comparing CPU and memory performance: Red Hat Enterprise Linux That the systems achieved on both parts of the benchmark. We ran the rate version of these benchmarks. Which runs multiple instances of the benchmark to assess server performance, is alsoĪvailable. SPEC CINT®2006 measures andĬompares compute-intensive integer performance, while SPEC CFP®2006 measures andĬompares compute-intensive floating-point performance. SPEC CPU2006 benchmark consists of two benchmark suites, each of which focuses on aĭifferent aspect of compute-intensive performance. When we tested CPU performance, we found that the server running Red HatĮnterprise Linux 6 scored up to 5.1 percent higher than the Microsoft Windows ServerĢ012 solution on the SPEC CPU2006 benchmark, both out-of -box and optimized. Testing the CPU with SPEC CPU2006 and LINPACK For details on how we tested, see Appendix B. We ran each test three timesĪnd report the results from the median run. Multiple tuning parameters to deliver optimized results. Solutions with out-of-box (default) settings, and then we tested those solutions using The memory bandwidth of the two solutions. The solutions using the different operating systems, and the STREAM benchmark to test The SPEC CPU2006 benchmark and LINPACK benchmark to test the CPU performance of We compared CPU and RAM performance on two operating systems: Red HatĮnterprise Linux 6 and Microsoft Windows Server 2012. Performance in nearly every test, outperforming its Microsoft competitor in both out-ofĪ Principled Technologies test report 2Comparing CPU and memory performance: Red Hat Enterprise Linux We found that Red Hat Enterprise Linux 6 delivered better CPU and RAM To help you make that critical decision, Principled Technologies compared theĬPU and RAM performance of Red Hat Enterprise Linux 6 and Microsoft Windows ServerĢ012 using three benchmarks: SPEC® CPU2006, LINPACK, and STREAM. System can help your hardware achieve its maximum potential and enable your critical The performance of business applications. Random access memory (RAM) represent the two most vital subsystems that can affect Often defines system and application performance. MICROSOFT WINDOWS SERVER 2012Īn operating system’s ability to effectively manage and use server hardware Microsoft Windows Server 2012ĬOMPARING CPU AND MEMORY PERFORMANCE: RED HATĮNTERPRISE LINUX 6 VS. In our memory bandwidth tests, the Red Hat Enterprise Linux 6 solution outperformed the Windows Server 2012 solution at mid-range thread counts.īy choosing an operating system that can deliver strong performance on all subsystems out of the box and increase performance even more when tuned, you can ensure that you are giving your applications the necessary resources to perform well and providing your organization with a solid foundation for future growth.Ĭomparing CPU and memory performance: Red Hat Enterprise Linux 6 vs. When we used the LINPACK benchmark to test floating point performance of CPUs, we also found that tuning the operating system allowed us to get even greater performance out of the Red Hat Enterprise Linux 6 system. In our SPEC CPU2006 tests, the Red Hat Enterprise Linux 6 solution achieved consistently higher scores than the Windows Server 2012 solution. Throughout our CPU and RAM tests, we found that the open-source Red Hat Enterprise Linux 6 solution performed as well or better than Microsoft Windows Server 2012. Understanding how your system resources are utilized and how well they perform can be extremely valuable as you plan your infrastructure, making the selection of the operating system a pivotal decision that could influence your IT strategy for many years to come.
