The benchmarking was done on the following three computers:
1.   NEC Laptop (Versa Series), 32bit CPU: Intel® Pentium® M with 1.8 GHz.
      1GB RAM. Operating system: Cygwin under WindowsXP.
2.   Fujitsu-Siemens, 32bit CPU: Intel® Xeon™, 2.40GHz (Dual core).
      2GB RAM. Operating system: Linux Red Hat 3
3.   SUN X4100 M2, 64bit CPU: AMD Opteron™, Processor 280, 2.40GHz (Dual core).
      8GB RAM. Operating system: Linux Red Hat 3
