Command to create Emulator:
avdmanager create avd --force --name emulator --abi “google_apis/x86” --package “system-images;android-28;google_apis;x86” --device 10
Command to start Emulator:
./emulator -avd emulator -no-boot-anim -no-audio -verbose -gpu off
./emulator -avd emulator -no-boot-anim -no-window -no-audio -no-jni -verbose -gpu off -qemu -enable-kvm -cpu host -m 2G
tried with both the above commands. Same Result.
In the entry point, I am starting the android emulator with the above command and start appium server.
I am trying to run 10 containers simultaneously in the machine with the above configuration. But each and every container becomes slow and nothing runs properly. Running 5 in parallel works with out any issue.
I have given different values for CPU shares, but no luck. I came through selenoid , where the speaker says that he could scale up to 30 containers in a server with good configuration. But I am failing here to run just 10 containers in parallel.
Is there anything I am missing in the android emulator? I have tried quick boot also, but no gain. Using emulators with snapshot increases Image size and also increases Block I/O usage.
I can provide more data if necessary. Any Help ?
