Iris's loadedRegions format Memory Usage Excessivity

[R00tB33rMan]

Problem

We presently had roughly ~280 players online at the time of this heap. Although this is a lot of players, our heap still wound up retaining up to 37 GB in size, which is brutally high.

Here's an example of the issue:

Hopefully you can all manage to resolve this, as it's quite problematic!

We're using the latest release (3.0.0) iteration of Iris.

Solution

Rewrite loadedRegions logic and make it less aggressive and consumptive. We have over ~60 GB allocated to this instance, which should be more than enough.

Minecraft Version

1.21

Iris Version

3.0.0 for 1.19.2 - 1.20.2

Yea ik im already working days on fixing the current source code made it better but it solved 1 problem of the 3 the system is having so its a improvement

[RePixelatedMC]

Also this issue has been in iris since it got created lmao my guess is that tectonic plates didnt carry as much data as they do now so its only getting problematic since a year or 2

[R00tB33rMan]

Understood. Hopefully we can get this resolved soon, as my instance/server would likely perform remarkably better, without this overhead. If any assistance is needed, do not hesitate to ask.

Pixeldev branch has improvements you could try and use that

[R00tB33rMan]

Sorry for the late response! Running my fork with some other changes from other PR's, in addition to the latest changes from that branch. I'll let you know how it goes in the coming days!

[R00tB33rMan]

Going to be honest: The new branches upon my testing and constant upstreams only made the situation worse and continually crashed my servers (or froze them) for long durations.

Known issue it are alpha releases i found a major flaw and am reworking the entire system for a month already or more

[RePixelatedMC]
