[BENCHMARK] dbench based

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 ;-)
