## Profiling Minetest on Linux
|
||
|
|
|
||
|
|
We will be using a tool called "perf", which you can get by installing `perf` or `linux-perf` or `linux-tools-common`.
|
||
|
|
|
||
|
|
For best results build Minetest and Irrlicht with debug symbols
|
||
|
|
(`-DCMAKE_BUILD_TYPE=RelWithDebInfo` or `-DCMAKE_BUILD_TYPE=Debug`).
|
||
|
|
|
||
|
|
Run the client (or server) like this and do whatever you wanted to test:
|
||
|
|
```bash
|
||
|
|
perf record -z --call-graph dwarf -- ./bin/minetest
|
||
|
|
```
|
||
|
|
|
||
|
|
This will leave a file called "perf.data".
|
||
|
|
|
||
|
|
You can open this file with perf built-in tools but much more interesting
|
||
|
|
is the visualization using a GUI tool: **[Hotspot](https://github.com/KDAB/hotspot)**.
|
||
|
|
It will give you flamegraphs, per-thread, per-function views and much more.
