Getting to third-party domain to a list of first parties is now very fast. But if you want to find first parties with a particular third-party URI, that process can be slow if the third-party URI might be found on a lot of websites.
Example
cen.third_parties['facebook.net'] is near-instantaneous now, but if you want all first parties that specifically have 'facebook.net/sdk/en_us/sdk.js', you have to do something like:
first_parties_w_uri = []
for fp, obj in cen.third_parties['facebook.net'].first_parties:
if 'facebook.net/sdk/en_us/sdk.js' in [url for url in obj.third_party_resources]:
first_parties_w_uri.append(fp)
The slowness comes in querying potentially many thousands of first parties and checking for the URI you're interested in. We can make this sort of important query faster too.
