When I run two separate Android Virtual Devices using two instances of the Android emulator, the second device launched is extremely slow and laggy (the first device is fine). This slowness continues even after I kill the first device.
I also noticed the second device eats a huge amount of host CPU (around 230%) whereas the first device only uses around 30%.
My host runs Mac OS X 10.11.6 and has a quad-core i7 processor.
What could cause this issue?
