Same application in two different users


Let's say I log in as X, open firefox.
Then switch to Y, open firefox also.
Does linux launch firefox twice in memory, or does it know how to open once for both users?

the two users may have totally different access rights, and so has firefox when they start it. You have one instance of firefox running with the privileges of user X, the other with privileges of user Y.

So in terms of task management, they have to be two separate instances.
In terms of memory management, however, the kernel may decide to share the code segments among multiple instances of the same process in order to reduce the amount of memory needed.

Why not???
apps will work smoothly for more users same time, Linux is a pure multi user Operating system..
You need to take care about Memory only.(Review RAM usage)
