Do you mean CFQ? http://www.phoronix.com/scan.php?page=news_item&px=cfq-io-scheduler-iops-linux-4.2
Nope, BFQ !

Bye, Daniele.
Daniele, I installed available bfq as kernel module but so far I'm not noticing any impressive performance. I started three consoles, one Virtualbox guest (windowx XP) Thunderbird and Firefox and I observed a long period of HDD high spinning and a bit of system freezing. I still have the parameter vm.swappiness=10 I don't know if I have to set it as per default. Anyhow I will let bfq scheduler activated for a week or two to see if it is better or not for my installation. marco@linux-turion64:~> cat /sys/block/sda/queue/scheduler [bfq] noop deadline cfq
Hi!
You forgot to tell us how much memory has your system.
Because with less memory system You have higher IO on the hard disk.

Hi Juan,
I have 4G RAM and 8G SWAP.
This is the explanation because you has: "HDD activity led is always on during high IO activity and system sometimes get unresponsive or in the better case very very slow" Regards -- USA LINUX OPENSUSE QUE ES SOFTWARE LIBRE, NO NECESITAS PIRATEAR NADA Y NI TE VAS A PREOCUPAR MAS POR LOS VIRUS Y SPYWARES: http://www.opensuse.org/es/ Puedes visitar mi blog en: http://jerbes.blogspot.com.ar/ -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
