I've been testing i2pd 2.46.1 through Tor with i2p+Snark (OpenJDK 19.2 guix pack) and Qbit.
The good news is that they do feed of each other for torrents and the downloads are faster.
i2p+ Snark 2.3

The bad news is that tunnel creation rate dropped to 44% from close to 60 and the surfing of sites becomes extremely slow.
Do NOT go into mixed mode (i2p/tor/clearnet) with qbit because it takes less than 15 minutes to be discovered. Tribler does a much better job for clear-net pirate torrents hands down. I'm not trying to bash Qbit which is the BEST clear-net torrent client. Just have the facts from my location.
