	Could you please recommend me a reading on both architectures to
	understand differences between them. I read here that BSD paging has
	some drawbacks to AT&T one (used in Plan9). And I want to make this
	clear for myself.

The discussions here were talking about many-years-old
systems.  I don't think anyone even mentioned Plan 9's VM system,
which is just about the simplest thing you could imagine.
The BSDs have oodles more ``features.''  I'd look in
www.researchindex.com for the latest stuff, and in McKusick et al.
(Design and Implementation of the 4.4BSD OS) for older stuff.
You can decide for yourself whether Plan 9 needs any of it.
