Can we have more than one program sharing the available physical RAM without paging if they are small enough?

LiteBSD: yes. RetroBSD: no. That is the main difference between the two systems - the memory management and virtual addressing systems.

Hi Wiz,

I assume we can now easily edit very large files.

It mostly depends on how smart the text editor is. There is no need to keep the whole file in the memory. For example, /bin/re editor allocates only one byte per every line of the edited file. On RetroBSD, it allows to edit files of up to 50000 lines, or about 1Mbyte of typical C code. This is all in fixed 96kbyte user space, without paging.

With paging it can do much more, of cause.
