Given the points made in the other answer about caching, but not in relation to the null check, try ordering the references to the BranchNodeData fields so that the first reference allows all of the following fields to be loaded into the cache.

That is, I assume the Jitter, or the CPU, is not smart enough to load "backwards" to cache SplitInputIndex, SplitValue and Child1 when Child2 is referenced first in the current code.

So either change the order of the fields in the BranchNodeData class, or change the set; if ... overwrite; to an if ... else.
