Flash Filesystem Benchmarks

Free Electrons has performed flash filesystem benchmarks, with funding from the CE Linux Forum, and presented the results at ELC Europe 2010.

Test methodology
See our ELCE 2010 presentation for complete details and benchmark results.

Test automation scripts
See this page for more details.

Free Electrons created Python scripts that automate the execution of commands through a serial line (including bootloader and kernel booting), and measure the time taken to execute these commands. The scripts were designed to be generic, and support for new boards can easily be added by creating board specific Python definitions.

A first version of these scripts can be found on (link outdated), and are released under the terms of the GPLv2 license. Working board automation files are provided for the CALAO USB-A9263-C02, Beagle and IGEPv2 boards. An ARM root filesystem containing all the filesystem utilities is also given in the same location.

A description of what these scripts measure, and how, is available here.
