Thanks for the reply, yes longer than I expected but useful – maybe I had to say that I saw all the videos to make it a little shorter.
Yes, the rescue instruction is a good killer.
I have the impression that the spiller with 16 buffers on a Gold with 32 belt positions suffers from a lot of pressure, because also the inner instruction produces “a new belt” and causes work for the spiller. Considering that 80% of belt values are used immediately and only once, it seems that there are a lot of belt positions with values that can be killed to prevent work for the spiller. Oh well, you are right and we have to wait for the hardware to see if the pressure on the spiller is an issue or not. My patience is just a fraction larger than yours 🙂
