>Checking every network connection against every possible Tor node takes time. This is fine if you have a slow network or low traffic volume, but it doesn't scale well for high-volume networks

What? I can't tell if this is sarcastic or not. There's only around 3000 tor entry nodes[1]. This is orders of magnitude smaller than the number of entries in the internet routing table, which is around 800k. This means at the worst case, if you're an ISP, you can block tor nodes at the router level with virtually zero impact.

It’s no problem, he has some regexs you can put in your DPI system to catch the connections instead. Regex is cheap right? Especially when it is long and complex.

It's like people haven't invented a Bloom filter yet so you can add it in front of a hash table....
