    The `prep-script.sh` will setup the latest Node and install the latest perf version on your Linux box.

    When you want to generate the flame graph, run the following (folder locations taken from install script):

    ```
    sudo sysctl kernel/kptr_restrict=0
    perf record -i -g -e cycles:u -- ~/sources/node/node --perf-basic-prof script.js
    perf script | egrep -v "( __libc_start| LazyCompile | v8::internal::| Builtin:| Stub:| LoadIC:|\[unknown\]| LoadPolymorphicIC:)" | sed 's/ LazyCompile:[*~]\?/ /' | ./stackcollapse-perf.pl > out.perf-folded
    ~/sources/FlameGraph/flamegraph.pl out.perf-folded > node-flame.svg
    ```

    The data munging is to help expose the most important bits. There is still some play that I'm working with, but right now it seems to be working.
