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;

http://www.tux.org/pub/tux/benchmarks/System/unixbench/

UnixBench contains 9 kinds of tests:

  1. Dhrystone 2 using register variables
  2. Double-Precision Whetstone
  3. Execl Throughput
  4. File Copy
  5. Pipe Throughput
  6. Pipe-based Context Switching
  7. Process Creation
  8. Shell Script
  9. System Call Overhead

lmbench

The LMBench home page is at: http://www.bitmover.com/lmbench/ and/or http://lmbench.sourceforge.net/
The sourceforge project page is at: http://sourceforge.net/projects/lmbench

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
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/*
