For those who enabled HAXM and the emulator still works slow here is what you should do:

1. If Avast antivirus is running on your computer, it is most likely the culprit.

as per HAXM Release_Notes.txt (Version 7.5.2):

• On Windows, Avast Antivirus may interfere with HAXM and cause Android Emulator or QEMU to run very slowly. A workaround is to uncheck "Use nested virtualization where available" in Avast Settings > Troubleshooting.

So open your Avast dashboard > Menu > Settings > Troubleshooting and disable "Enable hardware-assisted virtualization"

2. Give a higher priority to your emulator's process in the Task Manager:

   Locate your emulator's process in the Task Manager > Details tab:

   Right-click on it and Set Priority -> Above normal

Sorry that the screenshot is not in English but you got the point, right? That helped me significantly! I hope it will help you as well.

Also, one thing as per the Release Notes:

• On Windows 8, 8.1 and 10, it is recommended to disable Hyper-V from Windows Features in order for the HAXM driver to properly function.

In my case, I didn't have any "Hyper-V" feature on my Windows 8.1 but you probably should try it, just in case. To locate and disable that feature see this article: https://support.bluestacks.com/hc/en-us/articles/115004254383-How-do-I-disable-Hyper-V-on-Windows-
