[BENCHMARK] dbench based

["Paolo Ciarrocchi" <ciarrocchi@linuxmail.org>]

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:
