Hi Eduard,<br>
<br>
First, I owe you an apology; I stated "unavailable" in the review, but<br>
should've stated "unknown". We're in the process of trying to<br>
eliminate the reporting of infinite as it screwed up the weighing<br>
scheduler.<br>
<br>
Note that Zhiteng adjusted the scheduler so this isn't such a big deal<br>
anymore by down-grading the handling of infinite and unknown [1].<br>
<br>
Anyway, my suggestion to not use infinite is because in the coming<br>
weeks I'd like to remove infinite from the stats reporting altogether,<br>
and for those backends that for whatever reason don't know how much<br>
capacity they have use a more accurate report of "unknown".<br>
<br>
Sorry for the confusion, I think the comments on your review have been<br>
updated to reflect this, if not I'll do that next.<br>
<br>
Thanks,<br>
John<br>
