  Let $\mathfrak{P}$ be a topological property. We study the relation between
the order structure of the set of all $\mathfrak{P}$-extensions of a completely
regular space $X$ with compact remainder (partially ordered by the standard
partial order $\leq$) and the topology of certain subspaces of the outgrowth
$\beta X\setminus X$. The cases when $\mathfrak{P}$ is either pseudocompactness
or realcompactness are studied in more detail.
