good day, guys.
Sorry for my bad english, i am beginner yet.  Undecided
i have one doubt.

I decided create a shooter game like "Mushihime-Sama", not really identic that this but similar, the problem is in the test of paint elements in canvas, paint bullets in a continuous manner causes the player to move slow.

I use bufferstrategy for the level and bufferimage for the elements how the player, background, bullets and enemies. This problem only pass in ubuntu. In windows, the processor work much.

When i painted much elements in canvas, the player will move most slow?

what is the right way to paint In This Case?

PD. sorry if this doubt is already repeated.

CODE:
paint bullets:

public void paintBullets(Graphics2D g){
        if(bullets.size()>0){
        for(int q=0; q<bullets.size(); q++){
            bullets.get(q).paint(g);
        }
        }
    }

      spriteNames = names;
      height = 0;
      width = 0;
                colecImg= new BufferedImage[names.length];
      for (int i = 0; i < names.length; i++ ) {
        BufferedImage image = cargador.getSprite(spriteNames[i]);
        height = Math.max(height,image.getHeight());
      width = Math.max(width,image.getWidth());  
                colecImg[i]=image;
      }
                img.add(colecImg);
   }
