Just a curiosity... Isn't this related to the following BUGs:
Ubuntu server uses CFQ scheduler instead of deadline: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1008400
Kernel I/O scheduling writes starving reads, local DoS: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1064521
???
What can be done?
Edit the file: /etc/default/grub and add:
GRUB_CMDLINE_LINUX="elevator=deadline"
run:
update-grub reboot
Test it again...
Best, Thiago
