    Hi,

    I installed Cloudron using 1-click app in Vultr on a 1 GB HF instance.

    The memory usage is constantly above 1000 MB.

    No app is installed yet.

    Is this normal?

      @Ritesh Yes, as Cloudron is an App and uses resources (DBs & services) to manage itself and other apps, once installed.

        1Gb is indeed on the lower end for Cloudron to work well, however on modern systems (not just Linux), the indicator of used RAM very much depends. As long as there are enough memory pages just used for caching to speed up the system, it is generally a good idea to make use of all available system memory.

        If a system starts to swap out pages to disk, then it may make sense to increase the available RAM or limit individual apps to run their garbage collection more frequently.

        Basically those graphs have to be taken with a grain of salt to get a very broad view.

        I think, just the very basic meminfo manual for linux shows the involved complexity of providing general metrics on that topic: https://www.kernel.org/doc/html/latest/filesystems/proc.html#meminfo

          @Ritesh I suspect the issue is the low side of your memory to begin with, but wanted to also add that if you add more memory and still experience issues where it seems the memory or CPU usage is constantly high, you can reach out to Vultr's support as the issue may be on the hypervisor where some "noisy neighbours" may be happening which is starving your VM of resources. I had a similar issue a few months ago and they addressed it on their end after a few days.
