request for advice to increase throughput and lower latency

[Jelle de Jong]

Hello everybody,

I am using fairly standard setup with tinc version 1.0.31 on Debian 9.1 
and Windows Pro 7 clients, however the users complain that tinc is very 
slow. (they connect to smb shares and transfer files).

This is my configuration the client host files only have the keys.

Any advice and options to speed the connections up.

What Cypher will be better, I got CPU power and memory on the tincd 
server side.

Thank you all in advance,

Kind regards,

Jelle de Jong
