I started using dosbox for an old dos program. CPU cycles were high, 10-20%. You can tweak the settings using the config file. This changed when I installed dosemu which goes down to 1-5% for the same dos program.
Some dosemu features can be turned off ie net, sbemu, aspi, sdl etc in the compile-settings file before compiling
