Description

Since we do not strip the non-scalar resources during the resource arithmetic for quota, the performance can degrade significantly, as currently resource arithmetic is expensive.

One approach to resolving this is to filter the resources we use to perform this arithmetic to only use scalars. This is valid as quota can currently only be set for scalar resource types.
