<i>How does DJGPP compare with other DOS-based C compilers in terms of
efficiency of generated code?</i><p>

<i>Won't my program run much slower when compiled by djgpp, due to all
those CPU cycles wasted in switches between protected- and
real-mode?</i><p>

The quality of code generated by <tt>gcc</tt> with optimization turned
on (<tt>-O2</tt> switch to the compiler) is generally at least as good
as what you will get from top commercial products, like Borland,
Microsoft and Watcom.  Mode switches indeed have a certain performance
hit, but in most programs it is negligibly small, because only DOS and
BIOS services require such a switch, and most programs spend most of
their time doing other things.
