I was running a Bitcoin XT node, then when Bitcoin Classic came out, I switched to that. Now that Classic isn't seeming to gain a lot of traction, I decided to switch my node to Bitcoin Unlimited!
I am running it headless with the wallet disabled on a Raspberry Pi 2 with a 128GB USB flash drive to store the blockchain. I just compiled it from source and am running it with default settings. I know that there are different settings within Bitcoin Unlimited that can be changed, but I don't really know much more than that.
What I am wondering is if there is anything that I should change from the defaults, especially considering the hardware that I am running it from. I am not so concerned about the storage problem, I can eventually upgrade my storage from the 128GB flash drive, but is there anything I should change to make it run better and be more helpful to my peers and the bitcoin network?
