Shouldn&amp;#x27;t &amp;quot;Total Time&amp;quot; remain constant-ish until the number of threads exceed the number of cores? Why does time increase linearly with the number of threads on a multi-core system? Or is &amp;quot;Total Time&amp;quot; here &amp;quot;CPU Time&amp;quot; and not wall clock time?</text></comment>
