Thread is running slow for game!

Hi!

I'm currently porting the dedicated server for our game from win32 to linux.

After fighting my way until it compiles and run... i get extremly slow response from the linux server.

If i connect through LAN, i get like 700~900 ping.

The game is setuped like this :

- The main program is a console app waiting for input to interact with the game server
- The game logic itself is spawned in a thread

In win32, with default thread parameters, everything works perfectly.
But i suspect that i'm not setting up my pthread accordingly for linux.

Here is how i create the thread :

		pthread_attr_t threadAttr;	//attribute for parameting the linux thread
		pthread_attr_init(&threadAttr);
		pthread_attr_setinheritsched(&threadAttr, PTHREAD_EXPLICIT_SCHED);
		pthread_attr_setstacksize(&threadAttr,4000);  //reserving a 4 meg stack for the game
		pthread_attr_setschedpolicy(&threadAttr, SCHED_RR); //trying to
		sched_param schedparam;
 		schedparam.sched_priority = 99; //if i put 100 here the thread doesnt work
		pthread_attr_setschedparam(&threadAttr, &schedparam);
		
		if(pthread_create( &threadID, &threadAttr,(PTHREAD_START_ROUTINE)pFuncter, pParam))
		{
			perror("Thread Creation");
			return false;	
		}

i even tried to run this as root to make sure it wasnt something interfering with my user rights.

Thanks for any suggestions
