sorun:

core2duo islemcili serverda bol ram ve disk var
ICH7 chipseti yuzunden linux disk performansi yerlerde surunuyor
diskler sata olmasina ragmen
hda1, hdc1 vs vs diye gozuyor centos kurulumundan sonra.

Sorun acayip
cozum basit

nano /etc/grub.conf
kernel /boot/vmlinuz-2.6.18-194.11.4.el5 ro root=LABEL=/1 hda=noprobe hda=none hdc=noprobe hdc=none

Forza no probe 🙂

NOT: fstab icine bak direk alakali birsey olmasin hda li falan, Disk Labelleri guzeldir.

sonuc:

hdparm -Tt /dev/sda1

/dev/sda1:
Timing cached reads: 10864 MB in 2.00 seconds = 5437.80 MB/sec
Timing buffered disk reads: 220 MB in 3.00 seconds = 73.32 MB/sec

gayet iyi dandik makina icin 🙂
