Ok daar zitten dus al wat gaten in mijn installatie.
Ik heb 64Bit geinstalleerd want in heb idd 4GB erin zitten.
Verder heb ik nu Cool & Quit disbaled in de bios
Nu geeft cpu-info idd 2600Hmz aan...das dus al beter
Mysql is alleen nog steeds niet bijstersnel.\
Waar kun je binnen linux die performance mode instellen?
Kan het niet vinden
heb schijbaar geen /etc/cpufreqd.conf
Ok die heb ik nu wel..na aptitude install cpufreqd
ik zie wel een aantal processen
root        84     2  0 20:39 ?        00:00:00 [kondemand/0]
root        85     2  0 20:39 ?        00:00:00 [kondemand/1]
root        86     2  0 20:39 ?        00:00:00 [kondemand/2]
root        87     2  0 20:39 ?        00:00:00 [kondemand/3]
en
root        88     2  0 20:39 ?        00:00:00 [kconservative/0]
root        89     2  0 20:39 ?        00:00:00 [kconservative/1]
root        90     2  0 20:39 ?        00:00:00 [kconservative/2]
root        91     2  0 20:39 ?        00:00:00 [kconservative/3]
Ik wordt niet wijzer.
De mysql instellingen op deze machine zijn nu hetzelfde als op de oude.
Toch doet het inlezen van een dump er op de oude +/- 10 seconden over en bij de nieuwe 45 seconden.
Das toch wel erg veel verschil..
pff zelfs het droppen duurt lang
Oude machine
mysql> drop database syntec_dumptest;
Query OK, 236 rows affected (0.57 sec)
Nieuwe machine
mysql> drop database syntec_dumptest;
Query OK, 236 rows affected (14.07 sec)
Hmm das niet best
Wel is de oude mysql 5.0.67 
en de nieuwe
mysql 5.1.41
Overigens werkt cpufreq-info ook niet
