Benchmark Programs
Here are some different programs for performing benchmarking.
Note: It is important to recognize that benchmarks between systems may
be misleading. Benchmarks should primarily be used to determine
differences in performance for different software configurations on the
same hardware system.

Unix Bench
FYI, the URL to the UnixBench is as follows;
OLD site:
http://www.tux.org/pub/tux/benchmarks/System/unixbench/
NEW site:
http://code.google.com/p/byte-unixbench/
UnixBench contains 9 kinds of tests:
- Dhrystone 2 using register variables
- Double-Precision Whetstone
- Execl Throughput
- File Copy
- Pipe Throughput
- Pipe-based Context Switching
- Process Creation
- Shell Script
- System Call Overhead

Instructions for lmbench-3.0-a9
(Adjust CC and OS according to your needs.)
cd lmbench-3.0-a9/src
make CC=arm-linux-gcc OS=arm-linux TARGET=linux
Make the whole lmbench-3.0-a9 directory accessible on the target, e.g.
by copying or NFS mount. Make sure the benchmark scripts can write the
configuration file and results, and also unpack a tarball used during
the benchmark (in case tar is not available on target):
chmod a+w ../bin/arm-linux ../results
tar xf webpage-lm.tar
To run the benchmark on the target:
cd lmbench-3.0-a9/src
hostname foo # make sure hostname is set, the scripts use it to name config and result files
OS=arm-linux ../scripts/config-run
OS=arm-linux ../scripts/results
This worked for me on a target using BusyBox v1.10.2 ash.
The results are written into lmbench-3.0-a9/results/, for each run of
the ../scripts/results a new file is created. You can copy the results
back to your PC and run various kinds of summary postprocessing scripts
from lmbench, e.g.
../scripts/getsummary ../results/arm-linux/*
