Description
I have seen a number of good presentations over the last year, regarding efforts to tune file systems for eMMC or SSD media. However, I have not seen a lot of concrete suggestions for code changes in the kernel, or for tuning changes for existing kernels that will enhance performance.
This project would consist of benchmarking a few different filesystems on SSDs, with different performance tuning options, and producing a document to describe filesystem tuning parameters and methods for flash media.
