[BENCHMARK] dbench based

[Paolo Ciarrocchi]

Hi all,
here the results of a simple dbench test.
The "core" of script is the following:

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

The scripts evaluates the average of 3 runs of dbench N.
The missing part of the script is just "logging".
If someone is interested I can send or post to lkml the whole script.

Ok, dbench is not the best benchmark but, finally, 2.5.41 is faster then 2.4.19 (from the "dbench" point of view ;-)

Hi all,
here are the results of a test based on dbench.
It runs dbench N three times and evaluate the average.

Something happened between 2.5.59 and 2.5.61.

[BENCHMARK] dbench based

[Paolo Ciarrocchi]

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:
