LMBench usage

Select lmbench package in buildroot menuconfig, 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. For example: 

$ cp -r $HOME/armadeus/buildroot/build_arm_nofpu/root/usr/bin/lmbench /local/export/usr/bin/

On the target do: 

# cd /mnt/host/usr/bin/lmbench/scripts

The first time, configure the tests 

#  OS=armv5tejl-linux-gnu ./config-run

When asked, use in order: 

MULTIPLE COPIES [default 1] 1
Job placement selection: 1
MB [default ] 8
SUBSET (ALL|HARWARE|OS|DEVELOPMENT) [default all] HARDWARE
then default value (except for result mailing, choose no) except
Processor mhz [default 189 MHz, 5.2910 nanosec clock] 192
FSDIR [default /var/tmp] /mnt/host/
Mail results [default yes] no

Then launch the test 

# OS=armv5tejl-linux-gnu ./results

Wait some time (1 hour ;-) ) Then parse the results file from your host (it requires Perl) 

$ cd NFSROOT/usr/bin/lmbench/scripts/
$ ./getsummary ../results/armv5tejl-linux-gnu/armadeus.*
