The usual re-mapping from the data section to the home section is not done and greatly improves performance.</p> <p>Fixed processes do not see the virtual machine model; each process must have its data at a different linear address. It is, therefore, not possible to run multiple copies of a fixed process.</p> <p>Fixed processes are suitable only for system server processes such as the file server, window server etc. since the majority of context switches involve these processes.</p> <section><title>See also</title> <p><xref href="GUID-8F1567B4-6957-5B93-9499-35489AD610F5.dita">chunks</xref> </p> <p><xref href="GUID-7287F1D4-023E-5C90-91E1-6D8DF78D8241.dita">virtual machine model</xref> </p> </section> </conbody></concept>
