Not going to stream at 100kbps at 1600x900 with a quality of 10. The CPU is probably thrashing away like crazy trying to fit enough detail in to make the stream look like... anything at all, at that rate.

Do a http://testmy.net/upload 6MB test while NOT streaming and post your results. We need to get you a realistic baseline bitrate to work with/start tweaking from. I'd also recommend downscaling at 1.25 (720p), and dropping AAC audio to 128 instead of 192 (it will still sound good; it's not MP3, aac is much more bitrate-efficient). Your preprocess time is fine, most of your frame-time is being spent on encoding and uploading. With more overall bitrate to work with, things will go more smoothly, almost guaranteed.

Also advised to set your buffer to match your bitrate, it'll smooth out network transmission.
