You should probably define what you mean by "too long". If you're new to these applications, it might turn out that the render time you're experiencing is par for the course.
"Yeah, but I've got a really nice computer!"
Irrelevant. It all depends on your AE version, the footage you're using, and what you're doing in AE.
I have already some experience (2 years) with the Creative Cloud including After Effects. However when I used to render Videos on my old lapop which had worse specs It wouldnt take that long. Also rendering in Premiere Pro with Effects is way shorter!
Im using the latest AE and Media Encoder and the footage is stated above!
Sorry for the frustration and unexpected behavior.

That is a likely observation. Sorry about that! As far as After Effects goes, it has undergone some changes regarding performance over the past couple of years. Some things used to be faster in the past than they are now. That said, the team is working on future versions which can provide better potential for performance improvements. We just have to be patient as that works goes forward.
What Dave said is actually correct. Different processes and codecs use the CPU and RAM with varying performance depending on the task at hand, like "which codec is used for decoding and encoding?."
Let me know if you need more info.
