Large multi-language TMs versus single-language TMs wordcount performance

Wordbee can have many target languages in its TMs but we tend to use single-language TMs as that's the way we've always done it.

I was wondering what impact a multi-language TM will have on analysis performance.  As we have large TMs and many-language projects analysis can take a long time.

If we have a 100-segment source document and are translating to two languages, DE and EL, and we have a TM with 35,000 DE segments and another TM with 37 EL segments you'd expect the analysis time to be proportional to 100x35,000+100x37.  But if both languages are in the TM is the analysis time the same or is it proportional to 100x35,000x2?
