SUMMARY
If speed is the most critical factor when an application writes text
to a window, then the application should take advantage of every
possible speed improvement no matter how minor. Therefore, when
writing text to a window in a time-constrained environment,
ExtTextOut() should be used instead of TextOut() because ExtTextOut() is slightly faster.
ExtTextOut() is the lowest level function that an application can call to output text to a window. On the other hand, TextOut() is
essentially a call to ExtTextOut() with wOptions, lpRect, and lpDx set to zero. Using ExtTextOut() may not result in a noticeable speed
difference; however, it is the faster alternative especially when the
application has a large amount of text to write.
