> This JIRA is plan to add following misc perf improvements:
> 1) Use final int in Resources/ResourceCalculator to cache
> #known-resource-types. (Significant improvement).
> 2) Catch Java's ArrayOutOfBound Exception instead of checking array.length
> every time. (Significant improvement).
> 3) Avoid setUnit validation (which is a HashSet lookup) when initialize
> default Memory/VCores ResourceInformation (Significant improvement).
> 4) Avoid unnecessary loop array in Resource#toString/hashCode. (Some
> improvement).
> 5) Removed readOnlyResources in BaseResource. (Minor improvement).
> 6) Removed enum: MandatoryResources, use final integer instead. (Minor
> improvement).
