Yeah these numbers are unreasonably slow, about two orders of magnitude slower than expected. On fine rasterization some of it may be #155 but even aside from that these numbers don't look good.
I will want to take a closer look at some point (I have a laptop 1060) but am underwater just at the moment, so make no promise when.

Ok, trying this on the 1060. It's definitely #155, as reducing the blend stack size speeds that up considerably. I'm not sure the results are as good as I'd want them to be, but I haven't dug deeply yet. I'm pretty sure the driver has changed, as this is not consistent with results I was seeing before on the same hardware, but it's possible my memory is hazy. In any case, I know I'll want to fix blend memory (#156) and also will do some tinkering to see whether any of the other recent changes (gradients, blending, etc) might have caused a regression in fine rasterization performance on this device.
Other than that, your numbers suggest that the GPU clock is really low. Ideally you can set that to a medium-high but stable value. In any case, it should be possible to use the Performance tab in Task Manager (assuming Windows here?) to see the value.

Closing this, as the blend stack changes have long since landed, and none of the recent performance measurement work is suggesting that there is an issue with rendering performance.
