A Joshi,

Big/huge segments do not hurt performance, they only consume space. Some queries (operations) against big segments can lead to "performance problems". So, I do not think that one should consider segment's size as an immediate performance problem.

v$session is not a segment you should worry about.

sys.source$ -- no way, it must live in system tablespace.
