Programmer Tfs 1.3 work with multi-cores

[Engradiel]

Hello everyone, I'm looking for someone able to optimize TFS 1.3 and make it run on multi cores.

I think it really is a good solution in the medium and long term, as it will not required such an expensive dedicated.

There is a serious error in the source or datapack that is consuming a lot of CPU

I believe it should be the tfs 1.3 engine + scripts + systems + spells and others

you will certainly have to pay a lot more to anyone willing to make tfs multi-threaded (if anyone is crazy enough to accept this job), than the amount of money will would waste paying for a better dedicated server

in short words: it's not easy and that is why it wasn't done in decades

I know it is not a discussion post, and we know that the work of Multi Threading is quite complicated and impractical in many cases.

I think TFS can be optimized a little for certain specific tasks, but converting the entire engine cycle into multithreading is impossible due to the logic of how things work in Tibia, When I say impossible I mean that there will be no benefit in it, even if it is multithreaded it would behave as a single thread literally.

If you want to use parallelism you'll be good to go with just the C++17 algorithms library.

First of all, tfs is not single-threaded and there are no other bottlenecks (except db maybe?) that could be solved with mt.
The game is synchronous, you want stuff to happen synchronously in most cases, or else you might end up wasting performance on, for example, building paths that are no longer valid.

I am using kondra's ot log to see the functions more used:

      3876       296       23.32684%       12.92029% std::bind(&Game::checkCreatures, this, (index + 1) % EVENT_CREATURECOUNT)
      2747     47142       16.53197%        9.15674% std::bind(&Game::checkCreatureWalk, &g_game, getID())
      2623     26006       15.79142%        8.74657% std::bind(&Game::checkCreatureAttack, &g_game, getID())

Maybe someone know how to optimize specific that one.

I am using a Ryzen 5 3600, 16GB, 250GB NVME
The server is baiak (fast attack and a lot of monsters together)
With 130 players the cpu is already 70%

I guess with 150 180 max the freeze will start...



This is not normal right? (I know there is no magic to process the entire game simultaneously, but I believe it is bad and can be optimized)
