Seems to me that the stress test, also known as Bitcoin Giveaway, has failed to harm the Bitcoin transactions in any way.
While Mem pool is quite large and tx back-log has also grown, it seems that the only back-log are the spam transactions them self.
Real transactions are going through as usual

I only made one transaction today. It is unconfirmed after 8 hours.
I sent it using "bitcoin-cli sendtoaddress ...", let bitcoin core select its own fee - I think it's meant to use "smart fees" now - and it decided to use a fee of 300 satoshis. FFS.
