Do you think a minecraft server (and multiplayer game servers in general) can benefit for running on a soft-realtime OS like Linux with the PREEMPT_RT patch?

Games often use their tick rate (iterations of the event loop per second) as a quality metric, and an rt OS should favor preemption and low scheduling latency over throughput... so maybe that should give a more fluid experience?

But the bottleneck for minecraft seems to be in memory allocations, so an OS that can schedule threads rapidly may not change much after all.

First, Minecraft would have to actually support multithreaded work properly. Here the issue is just plain throughput / computation. RT usually makes things slower, but more predictable. MC needs to go faster first.

it all depends on if you want the tick time to equal the wall clock time.
