+# Performance Profiling
+
+This document over time will be home to various guides on how to use various profiling tools to do performance analysis of Mesos.
+
+## Flamescope
+
+[Flamescope](https://github.com/Netflix/flamescope) is a visualization tool for exploring different time ranges as [flamegraphs](https://github.com/brendangregg/FlameGraph). In order to use the tool, you first need to obtain stack traces, here's how to obtain a 60 second recording at 100 hertz using Linux perf:
+
+```
+$ sudo perf record --freq=100 --all-cpus --no-inherit --call-graph dwarf -p <mesos-master-pid> -- sleep 60
+$ sudo perf script --header | c++filt > mesos-master.stacks
+$ gzip mesos-master.stacks
+```
+
+If you'd like to solicit help in analyzing the performance data, upload the `mesos-master.stacks.gz` to a publicly accessible location and file with `dev@mesos.apache.org` for analysis, or send the file over [slack](mesos.slack.com) to the #performance channel.
+
+Alternatively, to do the analysis yourself, place mesos-master.stacks into the `examples` folder of a flamescope git checkout.
