New page

On this page you will find performance results and informations on how to run performance tests on our board.

===LMBench usage===

Add lmbench package in buildroot, regenerate your rootfs and copy ROOTFS/usr/bin/lmbench dir to your NFS root export or to your MMC.
lmbench need a NFS link or the MMC to work as it needs a lot of storage place.

On the target do:

# cd /usr/bin/lmbench/scripts
The first time, configure the tests
# OS=armv5tejl-linux-gnu ./config-run
Then launch the test
# OS=armv5tejl-linux-gnu ./results

When asked, use in order:
MULTIPLE COPIES [default 1] 1
Job placement selection: 1
MB [default ] 8
then default value (except for result mailing, choose no)
