Answer #1
Max Con. (Connections per File) = If the filehost allows for multiple connections per file, you can increase this limit to increase the downloading speed of the file. This is basically what other download managers do. However most filehosts won’t allow this for free users.
Max Dls. (Simultaneous Downloads) = Amount of maximum files JDownloader will try to download at a given time. Again most filehosts won’t allow this for free users. However you can try to use different filehosters at the sime time if you are a free user.
Speed (Limit) = The amount of bitrate JDownloader will try to use if it can (i.e. 0 means unlimited, 10 only 10 kb/s will be utilized at most)
