Don't take my word for any of this, just ideas.

"half the size" - this might be due to Subversion using a more efficient
storage mechanism than CVS.

"twice the size" - I think this is normal because Subversion stores a
local copy of your content when checkout so that diffs to determine
local modifications are much faster (don't require network activity).
