6GB RAM is 50% of 16GB RAM?

[Rexima]

My system has about 16GB RAM, and when i assign 6GB RAM to one VM, the Dashboard Info says im using 50% of my RAM?

And when i want to use 2 VMs with each 6GB RAM, im at 98% usage and after some minutes one VM is shutting down.

 

Is unRAID using about 4GB of RAM

There is overhead involved in the VMs, and I've seen anecdotal evidence that the more cores you have allocated to the VM, the more the overhead is.

 

Not to mention if you happen to be running any plugins or docker apps and their own requirements

Mh okay thats not so good.

I disabled Docker and only one Plugin is running, and this is "Tips and Tweaks".

Did you also count the cache as part of the RAM usage?

[Rexima]

No, i just attached a Screenshot of my Dashboard.

I have at the moment two VMs running, each assigned with 4GB RAM.

And like you can see, i have about 71% of Memory Usage, but 8GB of 16GB Memory are 50% in my calculation. Its a huge overhead in my opinion.

So, who is using the other 21% of Memory?

As well  as overheads on each VM, you also have to allow for the RAM that unRAID is using to run the system (which is likely to be of the order of 1-2GB) and for disk buffering so the figures do not seem unreasonable.

Okay thank you for the explanation, sounds clear now.
