That would probably take me a day to encode a 10 min video, haha. It took me about 3.5 hours to do an 11 minute video at 29.97Fps, 8 Target, 40 Max, 2 Passes.
I'm saying that you should encode your video at the highest bit rate(to and extent) you are comfortable uploading, if that's what you're doing. If your are just keeping the video for personal use, then the bit rate is less of an issue, and you should use what ever you think is sufficient.
The average and max bit rates i mentioned were merely suggestions that work for me when uploading to YouTube at 30fps. If you're using a lower or higher fps in the final video, then you should adjust your bit rate accordingly(higher fps=higher bit rate needed).
Based on my past experience(not much IMO), rendering a video with 8Mbps will take just as long as 16Mbps(YMMV). If you want to check, render a 5s section of your video at 8Mbps and time it. Then do the same at 16Mbps.
You may also want to try using x264 -crf(Constant Rate Factor) to encode your videos. It should be more than twice as fast as using 2 pass, with the only disadvantage being you can't accurately predict the final file size and bit rate. But with some experience, you will be able to get it close enough. If you would like more information on how to do this, just ask me here. Ill provide some links, and some instructions/help for you to follow in order to get your workflow moving quicker.

If you don't understand it, don't worry. Just make sure you read through the basic parts, especially the recommended bit rates, and the part about frame rates.
