The last of these is the most relevant part here. As I recall, when
we do a copy, we currently:
1) Copy the relevant parts into the (client-side) buffer.
2) Draw the new bits.
3) Copy the buffer to the client.
Doesn't it use a simple XCopyArea() which is done completely on the
Server?
At least the xlib backend should be doing this, but I am unsure whether
there are paths where we don't hit this case. Both the scrolling of
the message area as wellas the message table are reasonably fast, no
excessive jerkiness or delay.
When on the same computer I stpart PRICE and siplay an image big
enough so that it needs to scroll (an image sized about as big as my
screen, so not an exceedingly big one either) and scroll (that means,
dragging the scroll thumb and moving it up or down) it feels extremely
jerky and blocky, even for small amounts (where the "new" image part
is relatively small). It is clear that the new uncovered part needs to
be tramsitted over the network.
