A flash filesystem tuning guide

Tim Bird has announced the availability of an extensive guide to tuning Linux for flash-based storage devices [PDF]. "This is the culmination of several months of effort, to determine the results of using different tuning options in the Linux kernel, with different filesystems running on flash-based block devices. The document was prepared by Cogent Embedded, and funded by the CE Workgroup of the Linux Foundation. In addition to describing different tuning options available, the document also gives methodologies for measuring performance on the filesystems and has extensive graphs showing the results of the different tuning options."
