This may be off-top, please advise if so
TL;DR
Running X clients (pyCharm, git gui, Eclipse) on a Debian 12 system with
Cygwin-X as the display server exhibits vast performance differences
depending on how the X session is connected. X-over-ssh is sluggish and
laggy, but the same apps are lightning fast in an xdmcp desktop session.
Details:
Cygwin/X Server: Ryzen 9 7940HS, 32GB RAM, Windows 11, fully updated
Client: Intel i5-1135G7, 16GB RAM, Debian 12, fully updated
Network: 2.5GB ethernet (verified with iperf3)
The speed difference is stark. With X-over-ssh Eclipse is unusable,
PyCharm barely so. When running in an xdmcp session both are blazingly
fast with no detectable lag.
What would make such a huge difference?
