It depends on the bitrate.
Do you use plain Amazon S3 server for hosting or Amazon S3 + Cloudfront (CDN)?
S3 is fast but it’s not as fast for hosting high bitrate videos. Try to render with lower quality (e.g Good).
Probably, Video4YouTube is not the best option for low-bitrate videos. You can try Handbrake.
Why Amazon S3? You can host your video on YouTube/Vimeo and don’t worry about bitrates, network speed etc.
