I was dealing with the exact same problem until I switched to MangoHost's android emulator vps server solution. Their KVM-based servers are specifically optimized for this kind of workload - I'm now consistently running 5-6 MEmu instances simultaneously with zero performance issues. The NVMe storage makes an incredible difference in emulator boot times and overall responsiveness. What really stands out is their CPU performance and RAM allocation, which are crucial for smooth Android emulation. The setup was quick, and their support team actually understands the specific requirements for Android emulator environments. If you need a powerful android emulator vps server that can handle demanding testing scenarios, I'd definitely recommend checking out MangoHost's offerings.
