2026-03-27 => IN PROGRESS: Optimizing Matrix data storage - PART 2

=> 2026-06-04: Now running the compressor on a seperate i7 Server with 400GB(!) Swap. Over 12k rooms are present. Expect some performance impairments.

I am currently working on optimizing the data storage of the matrix server.

Since this involves write and lock operations on the database the server needs to be shut down for some moments.

2026-02-13 => System stability should be fixed

I rebuilt the server and cleaned it completely. Temps look fine, installed RAM is now 3000MHz DDR4.

Continuing to monitor using stress-ng, Fixes to the networking issues are work in progress and have been partially applied.
