[Vivid][SRU]Pull Request: Storage driver performance updates for vivid requested in lp1445195

[Joseph Salisbury]

This pull request is for storage driver performance updates requested in bug lp1445195.
The bug is requesting these patches in all current stable releases.  However, Vivid is 
the only release that has acceptable testing results(See comment #47), so a future pull 
request will be done for the other stable releases once we get good testing feedback.
