I suspect that you need to set the type= in X11(): see its help page.
E.g.
'type = nbcairo' is the same device as 'type=cairo' without
buffering: which is faster will depend on the X11 connection.
Both will be slower than 'type = Xlib', especially on a slow X11
connection as all the rendering is done on the machine running R
rather than in the X server.
Basically, R's X11 device is now by default optimized for quality rather
than speed, and your unusual usage needs the reverse.

Hi,
I often work from home, running R on my office computer and displaying
interactive graphics on my home computer using X11. This was always more
sluggish than sitting at my office computer, obviously, but recently the
graphics transfer has become painfully slow -- so slow, that I now divert the
images to a postscript file and display that file remotely (which takes a
second or two).
I don't know what changed between the old days and now -- I may have
installed a new version of R and updated the o.s. (ubuntu) on both computers,
but am unsure of the timing. I realize this makes troubleshooting difficult,
but I am hoping someone can offer a tip on where to begin.
Thanks
