I've followed all the instructions, but syncing my full node is taking for-f'ing ever...

Hey. I'm trying to build a new full node, but finishing the initial sync is taking for-fucking-ever. The first 50% was downloaded in about 48h. Since then, my download rate is fractions of a percent per hour...

• I've done the port forwarding on my firewall.

• There are 20+ peers connected at various times.

• I have tons of CPU (4x2Ghz)

• Lots of Memory (16GB)

• 70+% free storage (2TB NVMe SSD)

• Gobs of Bandwidth (100Mbit fibre).

I've tried banning peers (1h to 1 week) that connect but don't send blocks, Disconnecting ALL peers to try and get all new ones

A lot of peers seem to connect and not exchange any information -- is this some lame type of Denial-of-Service attack?

I've also tried manually connecting to peers I know are local (both physical location and low ping times).

So... Is there anything else I can do, short of re-downloading the blockchain as a torrent?

Thanks!
