+BENCHMARKS, Redux (for NLS) ==============================================
+  December, 2011 benchmarks produced on a much more modern
+  platform containing:
+     Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz
+     SMP with 4 cpus
+  reflected in the substantially reduced elapsed times.
+
+  Tested as root with nice -10 and using only common fields
+  but rcfiles specified identical sort fields and identical
+  settings for the 'B', 'b', 'x' and 'y' toggles (even though
+  the defaults are not necessarily identical).
+
+  Each test was run outside of X-windows at a linux console
+  offering 48 rows and 170 columns.  This was done to reduce
+  contention which sometimes made comparisions problematic.
+
+  old-top = procps-3.2.8 (debian patched and memory leaking)
+  new-top = procps-ng-3.3.2 with NLS support
+
+  ----------------------------------------------------------
+   The following comparisons were run with
+      -d0 -n5000
+      140 tasks & 275 threads

+notes:
+ d  these represent the same anamoly as the original 'a' footnote
+ e  these represent the '1' toggle, where each of 4 cpus was shown
+      (not possible on the original uniprocessor)
+ f  every common field was turned on and all fields were visible
+ g  on a black and white display, sort column was shown in bold
+      (further proof of column highlighting improvements)
+ h  similar to 'g', but new top was showing scroll msg
+      (old top has no such provision)
