why is double dragon so slow when many sprites move?

when you start double dragon and let it run demo you notice that the second  fase of the demo (with the 2 green big dudes) it slows down very much

is it normal for this game?

From the Mame FAQ:

Hard Drivin', Metal Slug 2 and Double Dragon are choppy, but I have enough CPU power.

Although the FPS counter shows 100% speed for these games, they may appear choppy. This is true to the original — even the original hardware of these games struggled with them and therefore the choppiness is actually accurate emulation of these games. You may be able to get rid of it in some cases by using the -cheat parameter, hitting the tilde key and browsing the on screen menu until you find "CPU overclocking". This will run the emulated CPU faster which may or may not fix it. It may also cause the emulation to have errors, so don't bug people if overclocking screws up a game.
