Considering one of the listed options talks about "several kilobytes" of reduced size it's definitely not all a huge improvement. A standard stripping of debug information is probably one of the biggest and easiest steps. Using upx can also make a significant difference, but unfortunately not every OS likes the result. Mac OS just immediately killed my program when it was compressed like that.
