CPU usage problem

What is wrong with syncthing and its CPU usage? It uses about 40% of my 8350 and it doesn’t get it speed above 100mbit/s while bittorrent sync is running easy on 400-500 mbit/s with only a 2% cpu usage?

We have hashing and crypto on pretty much every step, where as btsync doesn’t. I think it doesn’t even have crypto on LAN. Also, has it finished scanning?

On WD My Cloud with dual-core ARM I see download rate of 1.7 MiB/s and 66% CPU usage. It seems to me that it will never reach even 100 megabits with current gigabit network interface.

Is it possible to skip some hashing&crypto at least on LAN connections? Or to add some configuration options to let user decide?
