Why is Android Emulator (qemu-system-i386) CPU usage so high (%360)?

I haven't used Android emulator for long time because of its performance. However, Android devs claimed that emulator is better now. Even better than a real device so I started using it. It works fine, but CPU usage is too high.

Emulator Version: 25.1.7.0

Android SDK Tools: 25.1.7

Host Operating System: MacOS 10.10.3

Normally CPU usage is OK, but it becomes very high after the laptop comes out of the sleep mode. In this case I simply re-start the emulator. It is very annoying. Somebody suggested to edit AVD config.ini to set

hw.audioInput=no
hw.audioOutput=no

but it didn't help in my case.

Edit

The probelm seems to be fixed in Android emulator version 26.0.3.0 (build_id 3965150)
