+
+    <para>As in LFS, each package in BLFS has a build time listed in Standard
+    Build Units (SBUs).   These times are relative to the time it took to build
+    binutils in LFS and are intended to provide some insight into how long it
+    will take to build a package. Most times listed are for a single processor
+    or core to build the package. In some cases, large, long running builds
+    tested on multi-core systems have SBU times listed with comments such
+    as '(parallelism=4)'.  These values indicate testing was done using
+    multiple cores.  Note that while this speeds up the build on systems with
+    the appropriate hardware, the speedup is not linear and to some extent
+    depends on the individual package and specific hardware used.  </para>
