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

Indeed, not a big deal for the network as a whole in the end

Hardware requirement to run a full node is increased however: mine is now using about 1 GB RAM (while meme pool size has decreased already) instead of 350 MB usually... CPU usage seems a little higher as well
In any case, that is/was to be expected with network growth
