I wouldnt be surprised if 1 full node can do 200 tps with 2 cores if software is slighly optimized.
Your extrapolation is wrong, CPU load from DAG traversal/analysis ~ TPS
3/2 - TPS
2.
Why dont you go and correct your own users of your own project
https://bitcointalk.org/index.php?topic=1216479.msg17903973#msg17903973Others by the way are not pure DAG but hybrid between blockchain and DAG. If by others DAG algorithm does not work, then is the blockchain used.
IOTA is perfectly designed for the M2M industry, internet of everything, but not only for this!
Will you correct the user, and tell him, "Correction, IOTA does not work on internet of everything any better than any other technology despite being designed for it"?
I'm still not convinced that Byteball is a pure DAG coin, to prove my position I would need to generate a lot of transactions on Byteball network to show that in certain conditions (related to DAG topology) TPS growth is negatively impacted by necessity to pick the main chain. If you compared Ethereum (which calls itself block
chain) and Byteball you would see that they don't differ much:

If you looked at IOTA you would see this:

I'm not interested enough to make sure that my assumption is correct, but you could help by generating a lot of transactions and posting here the topology of the resulting Byteball DAG. Try 10 TPS on the testnet maybe?
