Super mario 3D land slow

Hello, today I install the emulator citra to play 3ds games. So I lunch the game but at the first level the speed is arround the 70%! I think its not my computer. I dumped my system files.
My hardware :
CPU: i7-3770k
Graphic gtx: 1060
Mainboard: p8Z77-V PRO
Memory: 16gb DDR3 679.9MHz

So, hope you can help me !

Citra is in it’s early stages of development.

Most games don’t run at full speed even on the best computers.

The problem isn’t your hardware, but Citra isn’t optimized very well right now.
