5 months ago BDS: Performance between WIN and LINUX
We did a small experiment to evaluate the performance of bds under linux and windows.
Environment
- CPU: AMD EPYC Rome (x2 vCPU)
- Memory: 8GB
- Version: 1.20.51.01
- System: Debian 12 & Windows Server 2022 & Wine 8.0
- Seed: -7587006310728081808
Experiment
We created 4096 TNT (from 0,0,0 to 15,15,15) and detonate it at the same location (0, 15, 0). To avoid chance, we conducted the experiment three times under the same environment, the result is as follows:
| System | First(s) | Second(s) | Third(s) | Average(s) |
|---|---|---|---|---|
| Windows | 57.3 | 58.2 | 57.1 | 57.5 |
| Wine | 55.9 | 51.9 | 52.2 | 53.3 |
| Linux | 69.3 | 72.1 | 71.3 | 70.9 |
It can be seen that the time required for BDS to complete the 4096 TNT explosion calculations under linux is more than ten seconds longer than that under windows(not wine).
Possibility
This is just a simple performance test. It does not reflect all the performance of BDS on different platforms, but it is also representative to a certain extent (TNT explosion involves calculations of various systems). The reason for this situation may be due to the compiler optimization level when BDS uses clang to generate executable files suitable for linux.

We are planning to add support to the linux version of bedrock dedicated server.
Preconditions
We need perfect c++ header files generated from Win-BDS because the name mangling standard defined in the itanium c++ abi does not contain a complete declaration. The current header is close to perfection, but it has some shortcomings, such as some virtual functions are unknown or the order is incorrect. This problem also affects: #1041 #1429 .
