Disk I/O in Linux

Tags:
interfaces / buses / i/os

Overview The paper contains preliminary results from an investigation comparing Linux and Windows XP disk I/O using kernel-based software RAID on identical hardware. Windows XP performance is shown to be substantially superior to Linux performance, for reasons not currently understood. They developed a simple user-level RAID layer built on aio, and demonstrate its improved performance over the Linux software RAID implementation, but its performance is still lower than that of the Windows XP software RAID implementation. The alternative is to investigate various options for extending or improving the Linux kernel, which is likely to be a riskier and more difficult task.
