15     The <b>total</b> elapsed time between the display of the boot prompt on the
16     minimal CD and the display of the login prompt after the reboot was
17     <b>00:42:31</b> on our test box. Yes, less than one hour! Note that this time
18     also includes the stage3, Portage snapshot and several packages download time
19     and the time spent configuring the kernel.

58     Start by selecting nearby mirrors either by defining the <c>SYNC</c> and
59     <c>GENTOO_MIRRORS</c> variables in <path>/etc/make.conf</path> or by using
60     <c>mirrorselect</c>. You can also define the number of concurrent compilation
61     processes at this point.

71    
72     <p>
73     Now is a good time to enable or disable some USE flags. Run <c>emerge -vpe
74     world</c> to list all currently installed packages and their enabled and
75     disabled USE flags. Either edit <path>/etc/make.conf</path> or use the
76     following command to define the USE variable:

86     <p>
87     Recent versions of glibc use <path>/etc/locale.gen</path> to define locale
88     settings.

96    
97     <p>
98     Last but not least, you may want to alter the <c>CFLAGS</c> variable in your
99     <path>/etc/make.conf</path> to optimise the code to your specific needs. Please
100     note that using a long list of flags is rarely needed and can even lead to a
101     broken system. It is recommended to specify the processor type in the
102     <c>march</c> option and stick to <c>-O2 -pipe</c>.
103     </p>
104    
105     <p>
106     You may also want to switch to <b>~x86</b>. You should only do this if you can
107     deal with the odd broken ebuild or package. If you'd rather keep your system
108 nightmorph 1.4 stable, <e>don't</e> add the <c>ACCEPT_KEYWORDS</c> variable.

119     <p>
120     You might want to recompile your whole system twice to make full use of your
121     latest configuration changes. It would take quite a long time to complete and
122     yield minimal speed benefits. You can let your system optimise itself gradually
123     over time when new versions of packages are released. However, recompiling is
124     a still good idea from the standpoint of maintaining system consistency. Please
125     see the <uri link="/doc/en/gcc-upgrading.xml">Gentoo GCC Upgrading Guide</uri>
126     for a discussion on the benefits of ensuring a consistently built system and
127     world.
128     </p>
129    
130     <p>
131     Recompiling only the packages that have already been updated since the release
132     or that are affected by your new USE flags will take enough time. You might
133     also have to remove packages that block your upgrade. Look for "[blocks
134     <brite>B</brite> ]" in the output of <c>emerge -vpuD --newuse world</c> and
135     use <c>emerge -C</c> to remove them.

174     Depending on what your new Gentoo machine is supposed to do, you will probably
175     want to install server applications or a desktop system. Just as an example,
176     <c>emerge gnome</c> and <c>emerge kde</c> have been timed on the ~x86 system
177     installed as describe above. Both have been installed from the same starting
178     point.

180    
181     <p>
182     You should check our <uri link="/doc/en/">documentation index</uri> to find out
183     how to install and configure the applications of your choice.
