Google has identified that Cloud Workloads running on Ubuntu perform better using NOOP as the default scheduler. Google has requested that Google Cloud Compute (GCE) instances use NOOP as the default. [FIX] Add udev rule for GCE devices to use NOOP by default. [VALIDATION] 1. Boot Ubuntu instance on Google GCE 2. Confirm that the scheduler is deadline: $ cat /sys/block/sda/queue/scheduler noop [deadline] cfq 3. Install proposed udev package 4. Reboot 5. Confirm that schedule is now noop $ cat /sys/block/sda/queue/scheduler [noop] deadline cfq [RISK] This patch will affect currently running instances and on reboot they should see better performance. However, there is a risk that some users will experience a performance hit. [ORIGINAL REPORT] Per Google's request, Ubuntu instances should use NOOP as the default scheduler.
