Speeds up the local feed extraction, by fetching more feeds concurrently and only applying a large timeout after fetching the full channels. This is based on the idea that YouTube's RSS feeds (extracted by the generic
FeedInfo
) have no/much less rate-limiting, likely due to the nature of RSS readers. I couldn't find an explicit statement from YouTube about that, but it makes sense. I've also increased to amount of concurrently fetched feeds in my fork for the last couple of months and had no noticeable impact so far.A small timeout after each chunk is still applied, to be a good citizen of the web and not overwhelm/spam the server.
The used values may need to be adjusted in the future, either to allow for even faster extraction or throttling if a rate-limit is introduced.
