In lotus-bench sealing, why window-post takes longer than winning-post?

[Zengdewei1]

When I executed command lotus-bench sealing --sector-size 32GiB, I found that window-post takes 4 minutes while winning-post takes 2 seconds. Can anyone explain why?
my log is below.

The calculation process is completely different. It is normal to spend different time doing different things. If you are interested, you can look at the source code, but I don't think it's necessary

I agree that they are different but I do feel confused. In winning, 66 leaves are selected. However, in window, 10 leaves are selected. But I do agree that circuit of window is more complicated than winning. So my problem is, why so different though they are based on post?

Lol. i can't explain why they are different in details. maybe you can found out in code. I will post you if I find docs that can explain this.

In short WindowPoSt is designed to prove up to 2300 sectors, for WinningPoSt it is way less.
