Here are the kind of performance I see with v1.7.1.

1-of-3    51
2-of-3    54
3-of-3    35
10-of-30  105
20-of-60  224

I consistently see almost half download times for a 100 MB file with
K=20 with v1.7.1 than with v1.8.1. This looks like a regression of the
new immutable file downloader for large values of K.

I'll do that.
