There is a big difference between the Quadro and non-Quadro. Looks like the

Does enabling PBOs make any difference?

Bigger pipes will definitely help, up to a point. The compression

you can get will vary a lot

I dunno about that. My modest Quadro 600 can read back about a

I have seen some slides that suggest that nVidia cripples the readback

Well, it's important to understand that VNC will usually just send

update.) It will send a full
That doesn't ring true, but I have no way of verifying it, either. The
only Linux machine I have with a GeForce is slow in general (it won't
even memcpy() at more than about 200 Mpixels/sec), so it's not a good
basis for comparison.

Hi,
I have done a couple of experiments with very large displays (e.g. 7680x4800,
7680x3200) and the performance has (understandably) dropped significantly.
Are there any tricks to improving the performance or is it not worth trying? I
recall multi-threaded builds but have not had a chance to
Bigger pipes will definitely help, up to a point. The compression ratio
you can get will vary a lot depending on the types of images that the
app is generating. I use GLXspheres as a sort of middle-of-the-road
approximation, since it has a realistic proportion of solid color and
smooth
