First benchmark

It's fine day in Tokyo/Japan!

Here is my first benchmark report.

1. sequential write

I measure sequence write speed with following script.

for i in 0 1 2 3 4 5 6 7 8 9 ; do dd if=/dev/zero of=$i.dat bs=1M count=1024;sleep 60;done

And I show you the my results.

Oops! It is only half performance under my environment!

2. sequential write

using script

for i in 0 1 2 3 4 5 6 7 8 9 ; do dd of=/dev/null if=$i.dat bs=1M count=1024;sleep 60;done

results

  

Oh, it is very few decrease of performance.
