Sandstorm.io is a manager of self-hosted applications. Managers of self-hosted applications are getting a huge interest lately. Quantum Hosting® has tried sandstorm.io for you. It was installed on this server:
1vCPU, 30GB SSD, 1GB RAM + 256MB vSwap, Ubuntu 20.04
The installation is eating all the RAM and swap file and the server is not responding during 8 minutes. Once you recover control of the server: the load remains high at 7 eller 8 with no installed apps.
Verdict: sandstorm.io is a snail and does not deserve any attention.
