    The article makes no mention if the benchmarks are taking advantage if multiprocessing is being used.
    My kernel is SMP by default on my T61 with an 8.04 install:
    Code:
    joshua@laptop:~$ uname -a
    Linux laptop 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008 i686 GNU/Linux

      PTS by design is written to utilize multithreading for applications that do support it. ie openSSL, compile tests, etc

        it doesn't matter what pts is written for, when the kernel is UP.

          Is the default ubuntu kernel not SMP? Thought that was pretty much default on all distro's now.

            The kernel used was SMP supported.

              Hi,

              A user at the german forum "www.ubuntuusers.de" did some tests with his Lenovo T60 (same hardware as the one in the Phoronix-test) on Ubuntu 8.10. His scores are dramatically better than the ones from the Phoronix test :

              LAME-MP3 : 60.62s

              OGG : 35.05s

              FLAC : 28.82s

              WAVPACK : 31.22s

              FFMPEG : 33.76s

              SQLITE : 24.21s

              SCIMARK (composite) : 290.28 Mflops

              Tandem-XML (write) : 54.22s

              How can it be that two systems with the same hard -and software got so different test results?

                Must be because of language support

                  I don't know... I am sorry if I am doubtful, but I typically use this command to ensure I have both core enabled:
                  Code:
                  cat /proc/cpuinfo

                  There is a huge difference between supported and enabled.

                    trooper09: I can assure you both cores were enabled and that cpuinfo reported both cores.

                      There's a few possible reasons... Do you have a link to his post / information?
