+====== Perf and Rust ======
+From [[https://rustc-dev-guide.rust-lang.org/profiling/with_perf.html|Guide to Rustc Development]]
+The basic perf command is this:
+<code>
+perf record -F99 --call-graph dwarf XXX
+</code>
+The -F99 tells perf to sample at 99 Hz, which avoids generating too much data for longer runs (why 99 Hz you ask? It is often chosen because it is unlikely to be in lockstep with other periodic activity). The --call-graph dwarf tells perf to get call-graph information from debuginfo, which is accurate. The XXX is the command you want to profile. So, for example, you might do:
