Comment 14 for bug 1064521

This is related to:

The outcome of bug 1008400 is (I think) 'this is fixed on Quantal by changing the default IO scheduler to Deadline'. Two problems with that:
1. We see the same problem (but to a lesser extent) on the deadline scheduler. It thus can't be just a scheduler issue.
2. Precise is the LTS release - hence we need to use Precise.

We are going to try the Quantal kernel with a deadline scheduler to see if it's any better.

I have asked our QA team to produce a script that regularly times MySQL updates to make testing this easier.
