I don't know. I don't know how often such comparisons are made in normal scenarios. You'd be the expert here.

I can probably synthesize a test to compare `_gnutls_x509_compare_raw_dn()` before and after, but that doesn't necessarily translate to real world numbers.

As for a cache, where would we store it? We just get a `gnutls_datum_t` and not something high level.

So wait and see if anyone complains?

I could also reverse the logic. I.e. do a binary comparison first (most cases), and do the slow comparison as a fallback.
