    2B2T needs this update.

    Please add it!

    This suggestion is very needed, for Minecraft itself too, not just serverside, but also the game itself. This option would allow us to be able to have more smooth experience playing large worlds in the game, where constant lighting and redstone updates are needed. This allows Mojang to expand on the possiblites of Minecraft without worrying about lag.

    As it currently stands, we no longer live in a world where game devs can be lazy and only use one core; those days ended more than a few years ago. Processors aren't scaling up in per-core performance as much as they used to, they're getting more cores instead. The fact that some servers have faced increasing problems because Minecraft still only runs one logic thread for several years now is unacceptable; this is even an issue in the modding sphere now, as I ran a game on 1.15 with a fairly restrained modlist... and came out with sub-30 framerates on a machine that can run almost anything the industry can throw at it. I have no doubts 1.16 would run even worse with mods.

    Beyond all that, though, I've also observed poor performance on my private server I run for my friends, and have had constant lag problems despite running on good hardware and with only a handful of people. That's... depressing. And though I haven't had much time to test, I suspect the only reason the server hasn't started running even worse with the move from 1.14 to 1.16 is because I also moved from Spigot to Paper in the process.

    This needs to happen. There's no excuse. It doesn't have to happen all at once, though. Start with threading dimensions separately, that should be a fairly easy starting point. 1.17 for the first steps, no later.

    Forget a cave update! *This* is the most important thing Minecraft needs!

    This is even a problem when i play single player, no mods at all, the client server sometimes cannot keep up with itself because it only uses one core of my computer

    I totally agree, this is exactly what servers need. 

    Minecraft's community is important, as far as I'm aware, so enabling servers to run a significantly high amount of players is actually needed.

    I can understand why people can get..."passionate" with this topic; no one likes lagging servers and those where you can find many people to play with usually are the funniest.

    This is not a brand new issue, it's been years since a fix was needed.

    Please, Mojang, understand that we are the community, we are constantly playing the fantastic creation you've given us. So we are the ones that can tell you what annoys us the most.

    Mojang, you were the one that told us to do whatever we want, to create our wildest imaginations...that no one could tell us what we can or cannot do.

    So, please allow us, your loyal community, to create magnificent large servers where we can play without having enormous performance issues.

    Please prove to us that you really listen carefully to your community.

    Thanks for reading.

    Although this would require a massive overhaul of Minecraft's source code, without it, we're looking at some pretty poor utilization.

    you could even delay 1.17 2 years and give us multithreading instead and i'd be happy, because i know that it would need almost rewriting the entire game.

    Hytale is going to be a big competitor with Minecraft when it releases, and server functionality seems to be a big focus of theirs. If Minecraft were to implement multithreading for servers, I think it would create a rise in the quality of Minecraft servers, and it could be a reason someone would decide to continue to play Minecraft rather than switching over to Hytale. Minecraft could really use an update like this, as even the largest, most expensive servers have issues with lag in an over 10 years old game.

    Dedicate an entire update to just optimizing the dedicated server and giving more control over options on CPU intensive operations. 👍

    If this is available on the bedrock server, I don't think it would be that hard on the java server

    To those who call the game devs lazy for not doing this, remember that this is a lot more work than you might think, and name calling wont help. However, I am sure some of the tougher problems with this may be able to be solved better if the community can offer help, and not just with play testing. 

    The one of the biggest problems would be continuing work on the next update at the same time. And rebuilding the entire game will be a lot of work. So while this doesn't need to be rushed, it should be a priority.

    Imagine what we can do with so much more players on one map !

    As a Java developer, I don't think adding this feature would take THAT long...
    Maybe just a little bit at a time, but even just chunk loading and generation on a secondary thread would give a HUGE improvement in performance. (Thanks)

    Heck yes. We need this more than most things. I would actually take this over the mountains/dungeons update

    Some ideas I would like to add to this:

    1. GPU parallelization
    I can think of many things that can be optimized by using the parallel processing powers of GPUs, such as explosions and physics interactions. I'm pretty sure the technical side of people will find more things to parallelize

    2. Chunk loading
    On 2b2t, there used to be a plugin that refuses to load chunks when the player attempting to load the chunks are moving too fast. Hausemaster eventually banned elytras on 2b2t, so there is no need for the plugin anymore, but just imagine how much would server TPS for servers with people traveling really fast improve with this.

    3. Chunk caching
    Chunks that are frequently visited by members of a server, such as chunks containing a base or chunks for the Cowmercial district on Hermitcraft should be prioritized when loading chunks, and should also be stored in RAM or some other alternative storage for fast access. I mean, having chunks for a build load faster than other places is really great, and also reduces stress on the SSD/hard drive.

    Great idea, but has more potential

    It would be so amazing to finally get rid of these single core limitations, while it might be difficult it certainly has to be possible. It would be way more epic than any cave update could ever be. Please mojang just start working on multi-threading!

    Knowing that a server is still playable at around 200 players on the same map with one core ; having 64 cores would mean 12 800 players (of course this is probably not linear but you get the idea) So this is a needed update

    One year later, still no signs of this ever happening... Imo, I'd sacrifice new content, even something like a new dimension, just so servers can finally update past 1.12.2

    we really need this. performance has always been an issue, even in versions pre.1.13. although it was bearable and did not cause as much of a significant impact as versions after 1.12, it's still something that could definitely be improved on. doesn't even matter if it'd take a while to finish, it could easily be announced as a new major update to the game and take the place of a possible next major update that is intended to introduces more features.

    I truly believe optimizing Minecraft for multi-core handling is going to be a game changer for everyone in the community. People with worse PCs will be able to play much more properly without as many issues such as lag spikes and freezes, leading them to downloading mods to help boost their performance a bit. Servers would also benefit the most out of this,lowering maintenance costs for servers GREATLY while also boosting how well they will perform on average.
    It would also be great if Data-Packet transfer would be added, as it would allow players from different places around the globe to play unimpended by latency issues.

    I greatly hope this thread is taken seriously and something is done about this.

    One of the reasons as to why Minecraft became so popular was because of multiplayer servers, they should definitely add this and focus on servers more and give server owners more tools to work with.

    Totally for it! Mojang, please optimize your game servers. I really want to play on popular servers where the version is higher than 1.12.2

    Most of all great mods for Minecraft also stuck on 1.12.2, that`s a pity...
    Please, don`t hurry with next versions, fix this for 1.16 at least...

    Vanilla server core can't works normally when the players more than 10.
