Description Kyle Taylor 2018-05-30 17:15:22 UTC 
I use X11 forwarding over SSH regularly from a local server to load resource-heavy build-utilities like PyCharm and Google Chrome (e.g., with SSH -Y user@host google-chrome) . The connection I use to connect to my local server is peer-to-peer over Ethernet on a dedicated CAT5 cable. X11 forwarding is lagged -- to the point of being unusable -- when using KDE (default install of Neon 5.12).

On this same computer with Gnome Shell (default install of Ubuntu 18.04), this network configuration works fine and the X11 forwarding doesn't have any noticeable lag.

Wait! Sorry. It was my iptables filters. The list of things to block was ridiculously long and it was slowing down SSH traffic.
