This is the code of getNumeric():
...
It seems already optimized to do one lookup in the common case?

Thats not the code. you are omitting the first lookup!

> Spinoff from LUCENE-5616.
> See the example there, docvalues readers get a fieldinfos, but it doesn't contain the
correct ones, so they have invalid field numbers at read time.
> This should really be fixed. Maybe a simple solution is to not write "batches" of fields
in updates but just have only one field per gen? 
> This removes many-many relationships and would make things easy to understand.
