 <p>Thanks for all the help, and the answer I selected most closely answers the problem of 2 emulators running slowly. </p> <p>What it turned out to be was that I was using 767MB on an Intel HAXM emulator, and creating 2 of those went over the allocated amount for HAXM. After running 1 Intel and 1 ARM emulator, it worked. The error message was somewhat inconspicuous so I didn't notice it at first.</p>
