Does this one rush to update all feeds at once? I mean, I have, let's say, 50 feeds from a certain website and updating 50 in one moment results into "service unavailable" errors for half of such feeds. What does "Feed update threads" option do? Is it what I ask about, or not?
As the tooltip for "Feed update threads" select box says, it defines the maximum number of concurrent threads when updating feeds. Thus the scenario you describe is not possible.
