Created attachment 150240 [details] patch to top's man page top doesn't show CPU time's statistics if -d1 is provided.There was a brief discussion[1] in freebsd-hackers@ about this. However, the fact that this is not explicitly stated in the documentation is at least, to my undestanding, a violation of POLA. The complete solution would be to patch top so it's able to show those percentages even for -d1 (as the GNU's version does). Because there seems to be no interest in this, I provide a patch to the man page instead. [1] http://lists.freebsd.org/pipermail/freebsd-hackers/2014-November/046573.html
