Seems like an on-going topic of interest in the #saltr (I2P+) IRC chat (see sidebar) is optimizing individual I2P+ routers for carrying more network traffic. After some help from /u/z3d and /u/term99 my I2P+ router is humming along more efficiently now.
If you're running a router 24/7 you just may get some help optimizing it for carrying the most network traffic it can handle if you hop over on IRC.
This is more for fun/bragging rights as much as it is to help the actual network by having better optimized routers running 24/7.

First pictured downtime was moving my I2P+ router from one VPS provider to a new home with a better network. The other ones are just random router reboots from adjusting some settings.
