Understanding how your choice of operating system affects file system I/O performance can be extremely valuable as you plan your infrastructure. Using the IOzone Filesystem Benchmark in our tests, we found I/O performance of file systems on Red Hat Enterprise Linux 6 was better than the file systems available on Microsoft Windows Server 2012, with both out-of-the-box and optimized configurations. Using default native file systems, ext4 and NTFS, we found that Red Hat Enterprise Linux 6 outperformed Windows Server 2012 by as much as 65.2 percent out-of-the-box, and as much as 33.4 percent using optimized configurations. Using more advanced native file systems, XFS and ReFS, we found that Red Hat Enterprise Linux 6 outperformed Windows Server 2012 by as much as 31.9 percent out-of-the-box, and as much as 48.4 percent using optimized configurations.
Many applications are ultimately constrained by the I/O subsystems on which they reside, making it crucial to choose the best combination of file system and operating system to achieve peak I/O performance. As our testing demonstrates, with the file system performance that Red Hat Enterprise Linux 6 can deliver, you are less likely to see I/O bottlenecks and can potentially accelerate I/O performance in your datacenter.
