Actually, it increases the size of the shared pool by maybe 10k or so per process, so you might eat up an additional meg or so. The server creates additional state object structures to accomodate process and session information. Increasing processes also increases the burden on lgwr and pmon, since they have to scan process and session state objects to do their work.
