Traccar system requirements

Hello. I want to install traccar in Linux server.
What requirements must the server have for each configuration (CPU, RAM, disk space)?
Expected configurations:

1. 1000 devices, 50 users
2. 5000 devices, 50 users
3. 10000 devices, 50 users

In each configuration, it is assumed that each GPS device will send 6 messages per day, that is, every 4 hours.
Additionally, OpenStreetMap maps will be installed.
Unfortunately, I did not find information on the network to calculate the requirements. If such resources exist, I will be glad to receive links.
Thank you.

That's pretty low usage with reports only once per 4 hours. CPU doesn't matter in this case. 2GB RAM should be enough. Disk will depend on what data is reported and how long you want to store it for, but you probably don't need a lot either.

Imagine a tracker that reports every 10 seconds which 1440 times in 4 hours.

Now devide your 10.000 devices by 1440 = 7

So seven devices can actually generate the same amount of position data as your 10.000 devices that report a position every 4 hours :)
