When I did a speedtest with xsplit it said i only got 4800 kbit/sec upload to the german twitch server. That's why I'm rather confused.
Maybe the German Twitch server won't allow you to upload at more than 4800kbps. 50mbps is a fantastic upload speed, but you shouldn't stream at too high a rate, because the higher the rate you use, the more people there are who will be incapable of watching your stream because they have slow download rates. Twitch isn't like YouTube, you can't have it stream at a lower quality/rate than what you're uploading it (unless you're a premium member).

The huge video sizes result from uncompressed video. When you stream, xsplit or OBS or whatever you're using is actually compressing the video in real time, and uploading the compressed version. You can set Dxtory to compress also, just be aware that compression uses more CPU.
The upload rate you require to stream is highly dependent on the compression algorithm and quality settings you choose. Also, the rate at which you upload will vary, with spikes for when there's a lot of movement in the video, and very low when nothing is moving.
