Limited speed 100Mbps Down 200Mbps UP

[Christophe Vanlancker]

I have been running benchmarks on DigitalOcean with different droplets in different locations 
When using encryption it's expected to generally have a reduction in throughput.

Many things can come into play, optimizations, maybe crypto acceleration etc, but that's beyond my expertise.

Hello, 



I have installed Wireguard on multiple location, servers, on each of this server I have 1Gbps link, my problem is that I’m not able to get more that ~100-120Mbps for download and ~200Mbps Upload, any idea why? 



As a server I use CentOS 7 as for “client” I use Windows 10 with latest Wireguard client.. 



Thank you in advance, 

Cristian
