The protocol simply was not designed with slow or laggy networks in mind, from what I can tell.On Wed, Aug 18, 2010 at 5:43 PM, Alberto Canestrelli wrote:Hi, I have a problem with Cygwin. I am connecting from USA by ssh to the Hector supermachine in Edinburgh ( I write "startx" in Cygwin and then I use "ssh -Y v1acanes@login.hector.ac.uk" ). Everything works fine, the only problem is that the forwarding of the windows is very very slow.Hi Alberto, It would be useful if you could try a non-Cygwin X server (e.g. a Linux or Solaris workstation). If X from under Linux appears fast, then the slowdown could be between your network card and display (probably Cygwin's fault). If X from Linux is also slow, the problem may be with the propagation of the X protocol between your network card and Hector (probably not Cygwin's fault) .You could also try enabling compression with -C. I have found this to be a necessity when connecting with X over ssh between work and home even though the locations are quite near each other and plain text based ssh access runs fine without the compression.
