I will have to ask the engineers on this as there might be a trade off somewhere and I now that they had thought thru many variables.
Also there will have to be some test done to verify all before going into a release.
Update to initializing volumes w/ nice-ing. Engineers did try this with the past kernel 2.6.17 and it didn't work so well. They will look into with the latest kernel and if there are no issues or trade offs then you will see this in future releases.
Thanks guys for helping our engineers!
