We use the non-smp emulator on small ARM Linux boxes (single CPU).
I have tested the smp emulator over the last two weeks, here are my
- smp version increases VmSize by 10-35 MB, but VmRSS by only about 1 MB
- smp version is slower, but not critically (can still run our software)
- qemu-arm-static 2.8 has problems running the smp version
So we will stick to the non-smp version until OTP-21, especially because
of the broken qemu (used for test suite).
