As a contract with the CELF, we (Free Electrons) developed a flash
filesystem benchmarking suite ; it tests ubifs, jffs2, yaffs2 and
squashfs(over UBI+two different block transition layers). It has been
run on a Calao USB-9263 board and a IGEPv2 board and on 2.6.38, .39 and
3.0 kernels.

The results are shown as histograms and two different reportings exists:
 * filesystem comparison for a given board/kernel couple
 * kernel comparison for a given board/filesystem couple

All the details are to be found at:

Reviews of the test protocol, pointers to incoherent results or any
other comment is welcome.
We will keep posting more results.
