Let's try from the slowest to the fastest, using the command
fio --size=9G --bs=64k --rw=write --direct=1 --runtime=60 --name=64kwrite --group_reporting
The ouput from this test should match the column wMB/s of the command iostat -mx 2, executed during the test.

/etc/cups/printers.conf and change the ErrorPolicy for each printer from stop-printer to retry-job.Last week I was In Seattle for the first Debian cloud team sprint The aim of it was to streamline the producing of official Debian ready to use images for various cloud providers. The three biggest cloud providers were there (Google, Amazon, Microsoft Azure), and my humble self was here because of the work I have been doing producing Debian base boxes for Vagrant.
During the three days the spring took we did the following: * Reviewed the current state of cloud images and their build tools After a demonstration of the vmdebootstrap and fai-diskimage creation tools, agreed we should try fai-diskimage as a default tool. Since a consensus here seemed to be reached I refrained myself from advocating packer or virt-install too much * Reviewed the current state of cloud-init in Debian and considering its non working state in stable, thought about an upgrade in Debian Stable Agreed about having unattended super axes by default inside the team,and proposed it to debian-devel
* Reviewed all the bugs of the debian-cloud virtual package. As with probably every so sprint, getting to bring all the people in one room brings a lot of synergies which couldn't happen on a mailing list. Also we noticed a lot of interest for Debian from the respective cloud providers which is interesting considering Debian is "only" a community based distribution. Seattle is also a nice town, with lots of pine trees and bicycle lanes, looked to me like Canada, a troll statue(?) though I didn't have the time to see that much of it.
