Is 4GB RAM enough for Windows 10 64 bit?

According to us, 4GB of memory is enough to run Windows 10 without too many problems. With this amount, running multiple (basic) applications at the same time is not a problem in most cases. However, are you using the 64-bit version of Windows 10? Then you can use a maximum of 128 GB of RAM.

I would like to be able to do something like the /etc/limits on Linux – setting M90, for instance (to set 90% max memory for a single user to allocate). So the system gets the remaining 10% no matter what. Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

How to limit memory usage in a cgroup?

There are a bunch of different ways to set cgroup memory usage limits. How one goes about making a user’s login session automatically part of a cgroup varies from system to system.

So I opened terminall and typed into it ulimit command: ulimit -v 1000000 which shall be like 976,6Mb limitation.

What’s the downside of limit in bytes?

The downside memory.limit_in_bytes is that it counts files cached by the kernel on behalf of processes in the cgroup against the group’s quota. Less caching means more disk access, so you’re potentially giving up some performance if the system otherwise had some memory available.
