[BENCHMARK] dbench based

I ran a dbech based script.
The "core" of the script is:
for value in 2 8 16 24 32;
do
        log=${kern}$1.dbench${value}.$date.log
        echo $log
> ./log/$log
                for i in `seq 1 1 3`;
                do
                        echo $i ":" $value
                        sync;
                        sync;
                        sync;
                        ./dbench $value |grep Th >> ./log/$log
done;
        
         awk '{tot+=$2}; END {print "Average: " tot/NR " MB/sec"}' ./log/$log >>./log/$log

It runs dbench N 3 times and then it evaluates the average.

And here the results:
