Now we know who to blame thanks 
I think you can also blame Mojang. I believe Minecraft is not optimized for multi core processing. Today, with how advancements in data processing come in parallel computing instead of faster clock speeds, video games will have to either stick with less everything or get in the multi threading scheme. The PS4 is said to include a fast 8 core processor. Minecraft can use only 1 core. Imagine if the server could run on 8 cores...
Edit: Some processes run in separate threads, but it's far less optimized than it can be.
