Softether vpn slow7/27/2023 ![]() This depends on your average packet size, when you send On a GRE/IPsec link I observe no more loss thanĬan be explained by the header overhead added to each packet. When your link is slower and your router is faster, the loss will be much less. Then your loss is proportional to how fast the initial link was. ![]() So, when using encryption the VPN performance is limited by the encryption load on the CPU (this router does not have HW Accel for encryption)Īnd the VPN has a fixed maximum speed. It claims a 90% loss but it starts with a very fast connection and uses a very slow router. Where is all the throughput going? What are some suggestions as to better ways to link sites? Are there any other tweaking suggestions - or is the 90% loss just something I have to live with. IPSec and EoIP are out of the question because of the dynamic IP / NAT possibilities.įor SSTP I've ended up with max-mtu: 1460 and max-mru: 1420 with little to no improvement. I've tried OpenVPN and SSTP and both have the same ceiling for downlink speed. On the link I am testing with at the moment (a 10/1 LTE link) I can only achieve about 1,000 kpbs down. I'm confused as to why there is such a performance hit, and what my options might be for at least improving transfer speeds. According to this incredibly detailed testing by Rick Frey almost every tunneling possibility in the Mikrotik ecosystem has around 90% throughput loss. My plan was to have all those remote locations connect via a VPN to a core router, and tunnel their traffic over that connection. "Branch" offices (typically co-working spaces, some homes, mobile workers). We have several core routers housed in data centres in key cities.
