I2P is great for privacy but it sloooooow even much slower than Tor from my experience
Maybe there's fast node out there but who knows.... 乁( ⁰͡ Ĺ̯ ⁰͡ ) ㄏ
If you're using it to browse webpages on the clearnet then yes, it's slower, because that's not the use-case for i2p. I've seen speeds around 1MBit/s which isn't lightning fast, but also not terrible for an anonymous network.
