great job!

it only uses about 20 or 30% of the cpu on a 256*256 map with the cpu 
load betwen 80% and 130%
without any other AI player

before it wa susing up to 95% of the cpu  or more and that with a cpu 
load of 600% at least on a 512*512 map






I would like to make the test on the huge map i made, the migration 
one,  why are huge maps not working any more?
I cant play any huge map 512*512...




i'm doing other tests and i will tell the resutls on the forum.



for now at first view, it seems that the funtion that takes a lot is:

this part in engine::run:

           if (!globalContainer->runNoX)
           {
               // we draw
               gui.drawAll(gui.localTeamNo);

               //globalContainer->gfx->drawLine(ticknb, 0, ticknb, 480, 
255, 0 ,0);
               //ticknb=(ticknb+1)%(640-128);
  
               globalContainer->gfx->nextFrame();
  
               endTick=SDL_GetTicks();
               Sint32 spentTicks=endTick-startTick;
               ticksSpentInComputation=spentTicks-ticksDelayedInside;
               computationAvailableTicks=40-ticksSpentInComputation;
               Sint32 
ticksToWait=computationAvailableTicks+ticksToDelayInside;
               if (ticksToWait>0)
                   SDL_Delay(ticksToWait);
               startTick=SDL_GetTicks();
              
               net->setLeftTicks(computationAvailableTicks);//We may 
have to tell others IP players to wait for our slow computer.

 i try to see witch one inside this part is taking so much cpu time....


and also this function that takes 32% of the cpu!! almost:

               // here we do the real work
               if (networkReadyToExecute && !gui.gamePaused && 
!gui.hardPause)
                   gui.game.syncStep(gui.localTeamNo);

The slowest one in a game without any cmputer is this one:

                   // We store full recursive checkSums data:
                   gui.game.checkSum(net->getCheckSumsListsStorage(), 
net->getCheckSumsListsStorageForBuildings(), 
net->getCheckSumsListsStorageForUnits());


WOW, this one is taking betwen 40 and 50% of the CPU now!!!!!!  what is 
that??


the oter functions are taking less than 4% of cpu, but reember it is 
only a game with no AI or network players...
I hope i will be able to load the RMHM_no_Rush_Migration_Huge_Map and to 
test everythink more precise.
