Best practices for field names

[idanariav]

Hello,
I saw in the documentation
that every field has 2 versions, the "literal" version and the "sanitized" version. For example, the field "Related" would also have a "related" version that can be used in queries, and is meant to reduce errors due to inconsistency with capitalization or due to use of spaces.

Putting the issue of inconsistency aside, my question is whether it has any effect on computational speed, index size or any other resource related metric to have two versions of the same field? For example, I saw that when the field name matches the sanitized version, the page property keeps only the sanitized version (since they are identical).

Does that fact means that having lowercase properties without spaces leads to a smaller page object with less properties, which improves the plugins efficiency, or is it mostly negligible in terms of performance?

Thank you
