Indexing...?! Wait, WHAT O.O ...well, guess I'll check back tomorrow morning.
I am on a 100mbit link with a Friendlyelec NanoPi R6s (Rockchip RK3588 with a 4+4 core config of 1.8/2.4GHz respectively).
As for the node, I am using Bitcoin Core - it seemed to be best compatible with both Lightning and Monero stuff. Plus, it also seems to be the OG, so very trustworthy imo.
