performance concerns

Im writeing a plugin and im I'm worried about performance issus at this peace of code:

Code:java

Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(GrandTheftMinecart.getInstance(), new Runnable() {
 
            @Override
            public void run() {
                for(Cooldown c: cooldowns.values()){
                    c.getPlayer().sendMessage(c.getSecondsLeft()+"");
                    if(c.getSecondsLeft() == 0){
                        setWantedLevel(c.getPlayer(), 0);
                    }
                    else{
                        c.decrement();
                        for(Entity e : c.getPlayer().getNearbyEntities(16, 16, 16)){
                            if(c.getPlayer().hasLineOfSight(e)){
                                c.resetCooldown();
                                break;
                            }
 
                        }
                    }
                }
 
            }

this is my Countdownclass:

Code:java

    private class Cooldown{
 
        private final long lengthInSeconds;
        private  long secondsLeft;
        private final Player p;
 
        public Cooldown(Player p, long lengthInSeconds){
            this.p = p;
            this.lengthInSeconds = lengthInSeconds-1;
            secondsLeft = lengthInSeconds;
        }
 
        public void  decrement() {
            secondsLeft--;
        }
        public long getSecondsLeft() {
            return secondsLeft;
        }
        public void resetCooldown(){
            secondsLeft = lengthInSeconds;
        }
        public Player getPlayer() {
            return p;
        }
    }

What do you think?

 

ToastHelmi,
Like any another Developer, test it for yourself; if their are any issues you encounter feel free to ask for help.

 

Opacification
I'v already tested it by myselfe and it worked fine (with one player)
but I doesent hafe the operunity to test it with more players (like 20 or so)

 

How often do you run the task? And how much ram does your server has?

 

what performance issue you hit?

where are results of your benchmarks?
