+# Performance analysis with the Tracy profiler
+
+[[_TOC_]]
+
+## Overview
+
+From the Tracy manual:
+
+> Tracy is a real-time, nanosecond resolution hybrid frame and sampling
+> profiler that you can use for remote or embedded telemetry of games and other
+> applications. It can profile CPU, GPU, memory allocations, locks, context
+> switches, [...]
+
+- Sources are on [Github](https://github.com/wolfpld/tracy)
+- There is a [web demo](https://tracy.nereid.pl/)
+- You can [watch an intro video](https://youtu.be/ghXk3Bk5F2U?t=37)
+- You can [read the manual](https://github.com/wolfpld/tracy/releases/download/v0.13.1/tracy.pdf)
+
+## OAI Integration
+
+To enable Tracy, compile `-DTRACY_ENABLE=ON` in cmake. Note that `build_oai`
+has no native switch, but you can use `--cmake-opt -DTRACY_ENABLE=ON` instead.
+
+Furthermore, you will need the Tracy profiler:
+
+- Windows hosts: There is a precompiled `tracy-profiler.exe` on Github
+- Linux hosts: Compile tracy-profiler from source as described in the manual.
+
+Start the OAI executable you want to profile. Then, open the profiler, and
+click on connect to connect to the executable.
+
+It is also possible to collect data from within docker containers:
+
+- Open port 8086.
+- To collect CPU data, make sure that you run docker with `--privileged --mount
+  "type=bind,source=/sys/kernel/debug,target=/sys/kernel/debug,readonly" --user
+  0:0 --pid=host` or provide the corresponding options in docker-compose.
+
+## Instrumentation
+
+Instrumentation is done via the header `common/instrumentation.h`. A couple of
+places in OAI have been instrumented already, search for the macros mentioned
+in `common/instrumentation.h`.
+
+In short, main features already in use:
+
+- Measure specific code regions by surrounding them with `TracyCZone(ctx, true);`
+  and `TracyCZoneEnd(ctx);`.
+- Record individual "Tracy frames" (in the OAI context, that's likely one 4G/5G
+  slot) with `TracyCFrameMark;`
+- Plot values using `TracyCPlot(name, val);`
+
+More information about these macros can be found in the manual.
+
+Make sure to link `utils` into the static library you are modifying to get
+tracy header definitions.
