<p>Usage:</p>
<ol>
<li>Install gperf_tools (<a href="https://github.com/gperftools/gperftools">https://github.com/gperftools/gperftools</a>), probably packaged with your Linux distro.</li>
<li>Build with <code>cpu_profiler</code> feature.</li>
<li>Run the code, the <em>raw</em> output would be in the <code>./out.profile</code> file.</li>
<li>Install pprof for visualization (<a href="https://github.com/google/pprof">https://github.com/google/pprof</a>).</li>
<li>Bump sampling frequency to once per ms: <code>export CPUPROFILE_FREQUENCY=1000</code></li>
<li>Use something like <code>pprof -svg target/release/rust-analyzer ./out.profile</code> to see the results.</li>
</ol>
<p>For example, heres how I run profiling on NixOS:</p>
<div class="example-wrap"><pre class="language-bash"><code>$ bat -p shell.nix
with import &lt;nixpkgs&gt; {};
mkShell {
buildInputs = [ gperftools ];
shellHook = &#39;&#39;
export LD_LIBRARY_PATH=&quot;${gperftools}/lib:&quot;
&#39;&#39;;
}
$ set -x CPUPROFILE_FREQUENCY 1000
$ nix-shell --run &#39;cargo test --release --package rust-analyzer --lib -- benchmarks::benchmark_integrated_highlighting --exact --nocapture&#39;
$ pprof -svg target/release/deps/rust_analyzer-8739592dc93d63cb crates/rust-analyzer/out.profile &gt; profile.svg</code></pre></div>
