This post is adapted directly from material originally created for mhatta's medium blog. He deserves the credit for the OP. It has been updated in certain places where it refers to old versions of I2P as current and has undergone some light editing. -idk

Right after it starts up, I2P is often seen as a little bit slow. It's true, and we all know why, by nature, garlic routing adds overhead to the familiar experience of using the internet so that you can have privacy, but this means that for many or most I2P services, your data will need to go through 12 hops by default.

Also, unlike Tor, I2P was primarily designed as a closed network. You can easily access eepsites or other resources inside I2P, but you are not supposed to access clearnet websites through I2P. There exist a few I2P “outproxies” similar to Tor’s exit nodes to access clearnet, but most of them are very slow to use as going to the clearnet is effectively another hop in the already 6 hops in, six hops out connection.

Fram till några versioner sedan var detta problem ännu svårare att hantera eftersom många I2P-routeranvändare hade svårigheter att konfigurera bandbreddsinställningarna för deras routrar. Om alla som kan ta sig tid att justera sin bandbredd inställningar korrekt, kommer de att förbättra inte bara din anslutning utan även I2P- nätverket som helhet.

Justerar bandbreddsgränser

Since I2P is a peer-to-peer network, you have to share some of your network bandwidth with other peers. You see choose how much in “I2P Bandwidth Configuration” (“Configure Bandwidth” button in the “Applications and Configuration” section of I2P Router Console, or http://localhost:7657/config).

I2P Bandwidth Configuration

If you see a shared bandwidth limit of 48 KBps, which is very low, then you may not have adjusted your shared bandwidth from the default. As the original author of the material this blog post is adapted from noted, I2P has a default shared bandwidth limit that is very low until the user adjusts it to avoid causing issues with the user's connection.

However, since many users may not know exactly which bandwidth settings to adjust, the I2P 0.9.38 release introduced a New Install Wizard. It contains a Bandwidth Test, which automatically detects (thanks to M-Lab’s NDT) and adjusts I2P’s bandwidth settings accordingly.

If you want to re-run the wizard, for instance following a change in your service provider or bcause you installed I2P before version 0.9.38, you can re-launch it from the 'Setup' link on the 'Help & FAQ' page, or simply access the wizard directly at http://localhost:7657/welcome

Can you find “Setup”?

Using the Wizard is straightforward, simply keep clicking “Next”. Sometimes M-Lab’s chosen measurement servers are down and the test fails. In such case, click “Previous” (do not use your web browser’s “back” button), then try it again.

Running I2P continuously

Även efter justerad bandbredd, kan din anslutning fortfarande vara långsam som jag sa, I2P är ett P2P-nätverk. Det tar lite tid för din I2P-router att upptäckas av andra noder och integreras i I2P-nätverket. Om din router inte körs tillräckligt länge för att bli väl integrerad, eller om du stänger av den plötsligt för ofta kommer nätverket att förbli ganska långsamt. Å andra sidan, ju längre du kör din I2P router kontinuerligt, desto snabbare och stabilare blir din anslutning, och mer av din bandbreddsandel kommer att användas i nätverket.

However, many people might not be able to stay your I2P router up. In such case, you can still run the I2P router on a remote server such as VPS, then use SSH port forwarding.
