Why Emulator work Slow Compare to Real System?


Have you ever tried to see what happens when you run an emulator? I am assuming here that you already know about the emulator. If you don’t then read here what is emulator?

Let’s get back to the topic which is why does the emulator work slow?

Many of us think about it, but they we didn’t get the reason. With the user point of view, it seems quite difficult to understand it. Here in this post, I am not going to discuss the technical aspects of working of emulator. I will share only conceptual thing which will be enough to make you understand that why emulators are slow compare to real machine?

Why Emulator Work Slow?

In reality, an emulator is a software program which helps us to run non-compatible programs on the same machine. For example, if you want to run iOS games on your windows pc, but due to different system specifications you can’t do the same. There will always be a compatibility issue. The iOS is obviously having different specification than the windows. So directly it won’t get possible. However, what if one don’t want to buy an iOS device, then what to do?

This is where Emulator comes into the scene. It provides that compatible environment to run the apps based on different OS. To run iOS apps on windows platform, you can use any best ios emulator for pc. Just install it on your pc and deploy the iOS app you want to run on windows platform. While using emulator you will notice one thing that it works slow.

Let me explain you the reason….

The host pc on which you run the app is having different instructions set than the application itself. The instructions sets which application is receiving are solely developed for app itself. We can’t directly send the host machine instructions to the app. The app will not accept them directly. To remove such incompatibility issue, we use emulator. It translates the instructions received from the host machine to app readable form. This translation time slows down the process of emulation.

You can increase the translation speed still there will be speed loss. This event occurs because an emulator is just software, not a complete machine. The entire responsibility of running an app on different platform is on emulator only. It is not getting compatible physical resources for it.

The guest and host system are also get affected with the complexity of systems. The more complex systems need more complex coding to develop an emulator that can communicate between two different operating systems.

To be more simplified side, an emulator is a like a translator between two different language speakers. To enable communication between two different native speakers, translator has to work. They can’t communicate with each other directly. It increases the communication time. The same thing happens with the emulator. Hence, the processing time increase and it slows down the process of emulation.

Final Words:

I explained you the exact reason why the emulators are slow than the real machine. I hope you understood it and will get able to convince others with your concepts if someone asks you the same question.
