Content nodes are horrendously slow, I benchmarked a few and all public RPC nodes have very low throughput. I added a few extra checks to the transport layer and now at least it prints that the network is congested or there is a high load on the content nodes (talking about steem,supply).

Hm, seems the Linux patches are out, so it could in fact be what's causing the issue, further investigation reveals.

have a link for the patches? I will keep an eye on the server tomorrow.
