The problem that my patches address is delays in first request for data,
as well as clearing old data before the control is shown. At present the
control only lets requests go ahead when it is visible.

Realistically the patches will achieve the same performance as any new
system as you can't request the data before you know you will need it!

Well, I agree with that (but I would say that, wouldn't I? - or MRDA -
Mandy Rice Davies Applies - in another forum that I use - see
http://en.wikipedia.org/wiki/Mandy_Rice-Davies )

Whatever the new design, it will still need to have these changes in
place so that requests can be sent out as early as possible (and old data
cleared before the control actually appears!)

OK.
