Fatto fatto, avevo scritto di botto senza ragionarci su...

Dici? Mi sembravano un indicatore interessante!

Un portatile HP omnibook 600, PIII@800 o @350 quando lo uso con la sola
batteria.

Cmq, lo script ora e':

#/bin/bash
#value=$1
kern=$(uname -r)
time=`date -R |cut -d " " -f 6`
date=`date -I`
for value in 1 5 10 20;
do 
	log=${kern}.dbench${value}.$date.log
		> $log
		for i in `seq 1 1 5`;
		do ./dbench $value |grep Th >> $log
		echo .
	done;
	
	awk '{tot+=$2}; END {print "Average: " tot/NR " MB/sec"}' $log
>>$log
	echo "System info" >> $log
	cat /proc/cpuinfo |grep MHz >> $log
	cat /proc/cpuinfo |grep bogomips >> $log
	echo "Time: " $time "Date: " $date >> $log
done;

Decisamente piu' carino!

Ma guarda la cosa strana:
con il kernel 2.4.16:
Throughput 38.0326 MB/sec (NB=47.5407 MB/sec  380.326 MBit/sec)  10 procs
Throughput 39.2024 MB/sec (NB=49.003 MB/sec  392.024 MBit/sec)  10 procs
Throughput 38.1043 MB/sec (NB=47.6304 MB/sec  381.043 MBit/sec)  10 procs
Throughput 40.7555 MB/sec (NB=50.9444 MB/sec  407.555 MBit/sec)  10 procs
Throughput 42.1433 MB/sec (NB=52.6791 MB/sec  421.433 MBit/sec)  10 procs
Average: 39.6476 MB/sec
System info
cpu MHz		: 334.241
bogomips	: 693.04
Time:  22:29:10 Date:  2002-03-08

mentre con il .17

Throughput 21.9153 MB/sec (NB=27.3941 MB/sec  219.153 MBit/sec)  10 procs
Throughput 27.1003 MB/sec (NB=33.8754 MB/sec  271.003 MBit/sec)  10 procs
Throughput 28.2514 MB/sec (NB=35.3143 MB/sec  282.514 MBit/sec)  10 procs
Throughput 19.9951 MB/sec (NB=24.9939 MB/sec  199.951 MBit/sec)  10 procs
Throughput 20.3467 MB/sec (NB=25.4333 MB/sec  203.467 MBit/sec)  10 procs
Average: 23.5218 MB/sec
System info
cpu MHz		: 334.250
bogomips	: 686.48
Time:  22:07:32 Date:  2002-03-08

Bella differenza vero?
