Why is my Genymotion Desktop taking so long to boot a single device?

**"Why is my starter taking hours to boot up?"**

Based on Genymotion guidance, very long boot times for a single device on Genymotion Desktop are often tied to memory leaks and stability issues that occur after extended Desktop usage. Desktop is not designed for automated, long-running tests or running multiple devices for extended periods. For reliable long-running or multi-device testing, we recommend Genymotion Cloud/SaaS.

What you can try now:

- Restart Genymotion Desktop and, if possible, reboot your host computer to clear memory.

- Ensure you’re on the latest Desktop version (as of our latest notes, around 3.9.x) to benefit from fixes.

- Limit active devices during boot or disable non-essential services to free resources.

- If you need long-running automated tests, consider Genymotion Cloud/SaaS Cloud for cloud-based devices.

Quick checks to improve boot speed:

- Check that your PC has enough free RAM and CPU headroom.

- Update graphics drivers and enable virtualization features in BIOS/UEFI if applicable.

- See if any known-issues lists mention boot slowness for your Android image/hardware combination.

If you’d like, we can compare Desktop vs Cloud setups for your exact use case and help you pick the best option.

One quick question to tailor help: are you running Genymotion Desktop on Windows, macOS, or Linux, and how many virtual devices (including this one) have you booted simultaneously recently?
