A few weeks ago, Unity released ‘Megacity Metro’. This is a new sample project that, among other things, demonstrates the ‘Netcode for Entities’ network layer (for DOTS or ECS). I evaluated this project for my bachelor's thesis and carried out load tests. In particular, we wanted to know the maximum number of players that could be supported. We made video recordings of this to be able to present the results. The video is available on YouTube now!

Hey that's kind of cool, been waiting for someone to actually test this stuff out
Was about to suggest you post it over on the forums as I'm sure netcode folks would love to see it, but you already have
Did you ever try it on a dedicated host?

awesome!

It actually is running on a Linux machine and we connected 1700 clients from 6 different windows computers to it :)

is the video from a client then?

It is, yes. And there are no other processes running on it, only one client.

oh that performance is slightly more concerning for me then
i wouldn't have expected a client to spike so badly without much of a simulation

1700 thin clients or real?

ThinClients are exactly the same as normal clients for the server.

You're right, buut we also have to keep in mind, that Megacity Metro was only made for 128 players. It is not optimized for this amount of connections.

curious of what was performance on thin client side (without graphics). As in, were there any issues with performance on CPU side?
for clients I mean
for normal client it was clear that graphics did bottleneck things by a large margin

Like I said in the other thread, super cool. What are the specs of the server?
Would love some data on what happens there. Is it bottlenecking somewhere there too or is it just cruising along with 1700 clients?

We've posted some more information about the server in the forum.
The server is actually bottlenecking on the CPU from 900 clients on, but it can still keep it up to 1.7k. It is crashing because it runs out of ram. We couldn't test it with a better server, but we were already very satisfied with 1k+ clients. But I am pretty sure that for the simple project we will reach numbers way beyond 1k.

We didn't really look into the performance of the thin clients because we limited their frames to 15fps to minimize CPU usage. We had to do this to be able to spawn 1.7k thin clients. But there was no indication that they had any performance issues.

Super cool! Nice read.
So with more RAM, better server (afaik this is a mid-tier server right? ), all optimisations mentioned by nicky and a clean project you could reach thousands of players probably, on a single server. That would probably be some kind of record somewhere on a single server
