It has been said that the [http://www.linuxintro.org/wiki/FRITZ!Box_7312 FritzBox 7312]'s WLAN is okay for a flat, but too weak for a house. The FritzBox 7270's WLAN is supposed to be strong enough for a house, it has three antennas etc.. I wanted to test this. So I put my [[Latitude 2100]] into a cellar room and started the command
 +
iwlist scanning | grep -Ei "quality|essid"
 +
I used the same command with a FritzBox 7312 and with a FritzBox 7270 with the same laptop with the same distribution on the same position, same kernel etc.. I verified every result at least 3 times to make sure variance is low.
 +
 
 +
The results were

my QEMU benchmark

QEmu guest system openSUSE 10.2, command is 

1:time (for i in $(seq 1 1 10000); do echo $i>>file;done)
2:time (for i in $(seq 1 1 10000); do echo $i>>/dev/null;done)

my easy benchmark

Goal: Get a rough impression of system power Command is 

time (for i in $(seq 1 1 10000); do echo $i>>file;done)

Or if bash is not available, write a script that does this and call it using time

Linux kernel compilation

Here I compare the compilation times of the Linux kernel 2.6.27 over different platforms. As time I use the real time that I get from e.g. time make -j4. When comparing keep in mind

  • I am a lazy guy and use default installations for all distributions
  • some compilations are on the x64 platform, others on x32
  • different distributions bring different C compilers and library environments
  • some of the results are virtualized, some not
  • yes "" | make config produces a different .config file for different hardware
  • this is a real-world benchmark, not a synthetic one
    • this is primary a CPU benchmark, but disk I/O plays a role

Commands

Here are the commands for the benchmark 

wget ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.27.2.tar.gz
rm -rf linux-2.6.27.2
tar xvzf linux-2.6.27.2.tar.gz
cd linux-2.6.27.2
yes "" | make config
time make -j4

If the make command is different, it is notified in the results table.

KDE compilation benchmark

The KDE compilation benchmark was supposed to show the KDE compilation capabilities of distinct systems. However I use it less in recent times because compile time largely differs depending on

  • what libraries you have installed
  • what library versions you have installed
  • what KDE version you compile.

To resolve all this, I use my Linux kernel compilation benchmark.

WLAN

It has been said that the FritzBox 7312's WLAN is okay for a flat, but too weak for a house. The FritzBox 7270's WLAN is supposed to be strong enough for a house, it has three antennas etc.. I wanted to test this. So I put my Latitude 2100 into a cellar room and started the command 

iwlist scanning | grep -Ei "quality|essid"

I used the same command with a FritzBox 7312 and with a FritzBox 7270 with the same laptop with the same distribution on the same position, same kernel etc.. I verified every result at least 3 times to make sure variance is low.

The results were

device quality of WLAN
FritzBox 7312 31/70
FritzBox 7270 41/70

Wii

I have driven the Luigis Piste course on Nintendo Wii and chosen different cars and different figures (Bowser and Yoshi). Here are the times: Bowser in Offroader on Luigis Piste: 1.28 Bowser in Offroader on Luigis Piste: 1.28 Bowser in Offroader on Luigis Piste: 1.28 Yoshi in Nostalgia on Luigis Piste: 1.28 Yoshi in Bopper-Bolide on Luigis Piste: 1.28 Seems I always need 1.28 on Luigis Piste.
