Tixati to Tixati I2P performance is underwhelming to say the least.

Tixati to BiglyBT/qBitorrent/I2PSnark/Deluge perform extremely well but not Tixati to TIxati.

I have seen the same thing in clear-net seeding too.

Why is that so?

Maybe those peers are slow. You can't make a peer take more than it can handle, nor can you make a peer put out more than they have.

That's what I'm saying, only Tixati to Tixati is slow, rest are all fast.
Tixati to Tixati should be faster than other torrent clients because Tixati has preferrence for Tixati
