I would like to completely eliminate all outside factors in order to
have less disinformation to care about and compensate for when
working on this.

I specifically explained that this is *not* the purpose of creating
an artificial environment for testing and for development.
The goal is obviously real-world performance, but getting there will
be easier if as much noise as is possible can be removed from
measurements and data during testing analysis and development.
There is obviously a big problem somewhere, which may be easy to
find, but it will be easier to also spot other problems with hard
reliable reproducible numbers.

I'll try to make the point again; the purpose of a controlled,
artificial environment for testing and development is not to make
numbers look better, but to have a common reference for everyone, and
to have absolutely minimal interference with timing within the
library.
