Hi Marco,
Dears Tumbleweed users, gurus and hackers,
I would like to get some suggestions by more skilled people in order to improve my low IO disk performance because sometimes by using iotop I can see over 99% of disk activity especially when running VirtualBox and packagekit is updating the system.
HDD activity led is always on during high IO activity and system sometimes get unresponsive or in the better case very very slow.
I tried to change one ext4 parameter from [cfq] to [noop] without any noticeable improvements.
sudo echo noop > /sys/block/sda/queue/scheduler ISTR that noop would be beneficial for SSDs, but not for HDDs. Other

Best,

Would like to know if I can try some other tuning.
My HDD is an ATA 465,8G SAMSUNG HM501II ext4
Many thanks and regards!

Thanks for your feedback Robert! I rolled back to [cfq] now but want to try the parameter vm.swappiness which as default is =60 and set it to =10: cat /etc/sysctl.d/99-sysctl.conf vm.swappiness=10 Cheers, Marco N�����r��y隊Z)z{.���r�+�맲��r��z�^�ˬz��N�(�֜��^� ޭ隊Z)z{.���r�+��0�����Ǩ�
