Uhh the lag..

We have enough memory dedicated for the server, that's not the cause of our lag problem.
The server just can't handle everything that is going on ingame at the same time. It's as easy as that.

Adding everything that the server is supposed to do in one tick, takes longer than one tick should normally take, which is 50ms. Then the server will lag.
All entities loaded in the whole world, all chunk loading going on at the same time, all redstone contraptions, farms, water flushing, huge storage systems etc etc (the list goes on) added together is more than our server can handle.

I did find something yesterday, that may be fixed as of one hour ago, which had to do with entities, and was a bug in paper. The devs made a fix for it, and I updated simplex an hour ago. Fingers crossed it helps at least a little.

Other than that, we have no magic fix for this lag.
The best thing we can do, is to tell all players to not have farms running if it's not nessecary, not collect a TON of entities in the same area, and not have a million farms together in one place running at the same time. Also think about how you make redstone contraptions.

I dont know the exact reason for the lag, and most likely it's a bunch of things added together that makes the server lag.

To be honest, I'm tired of lag hunting, and have not much else to try right now.

Hmm, I guess you're right. But then again several complaints have been recorded about this and we can't just give up on such an important factor of game quality on the server. Anyway, I'm sure that some sort of changes will be taken inevitably and that you guys care about it as much as we all do. Also, I would like to say hats off to you for finding out about that bug and fixing it given how frustrating this process could be and that you've done your best after all. Let's never lose hope and we'll definitely be able to solve these problems sooner or later. Thanks for your honesty.

Honestly if I were not a minor, had a source of income and a bank account, I would've donated without hesitation because you guys totally deserve it. But until then, I could only help through giving my opinion and providing some ideas and suggestions to make the community better as each one of us should act within his limits. While some people would donate materialist values that could help with the development of the server overall, some others enlighten it with the interesting propositions which contribute then to the growth of the community. Either way, they're all doing their parts and I think even being part of this server and making the small acts would act as a donation to its community.. Well anyways that's about it. I hope that more donations will be given in the near future and I wish you best of luck.
