How do I check max memory utilization on Linux?
Entering cat /proc/meminfo in your terminal opens the /proc/meminfo file. This is a virtual file that reports the amount of available and used memory. It contains real-time information about the system’s memory usage as well as the buffers and shared memory used by the kernel.
Does Ubuntu use a lot of RAM?
Ubuntu uses as much of the available RAM as it needs in order to reduce wear on the hard drive(s) because the user’s data is stored on the hard drive(s), and it is not always possible to restore all of the data that was stored on a faulty hard drive depending on whether or not that data was backed up.

In this case you would need, either 32 Bit PAE or 64 BIT which support really big memory sizes.
How to create a user with limited RAM usage?
Is it possible to start applications with limited RAM and swap avaliable to them without creating a separate user (and not installing any special apps – having just a default Debian/CentOS server configuration, and not using sudo)? So I opened terminall and typed into it ulimit command: ulimit -v 1000000 which shall be like 976,6Mb limitation.
