Flash Filesystem Benchmarks 2.6.36

This page is part of the Flash_Filesystem_Benchmarks effort done by Free Electrons with funding from the CE Linux Forum.


 * The results below are old, and our test scripts have been improved, so we recommend looking at our results for newer kernel versions instead
 * These results were obtained on a CALAO Systems USB-A9263-C02 board.
 * See our ELCE 2010 presentation for complete details and graphical representations of those results.
