    2020For example, in a test build of LFS-9.1 on a Core i7-4790 CPU based system,
    2121using 4 cores, the following statistics were measured:</para>

    2727<para>As you can see, on the same hardware, the 64-bit build is only 3% faster
    28 and is 22% larger than the 32-bit build. If you plan to use LFS as a LAMP
    29 server, or a firewall, a 32-bit CPU may be largely sufficient. On the other
    30 hand, several packages in BLFS now need more than 4GB of RAM to be built
    31 and/or to run, so that if you plan to use LFS as a desktop, the LFS authors
    32 recommend building on a 64-bit system.</para>

    3838This is not directly supported in LFS because it would interfere with the
