Synopsis
Rather than just accepting poor system performance, you can use the
tools available in Linux to better understand the underlying causes of
those issues and suggest ways of resolving them. This presentation will
include:

- How to use tools such as the Linux kernel's perf tool to show what
regions of code consume the most processor time.
- How to identify areas of an application that most need to be
optimized.
- How modern processors work (just enough to better interpret
performance data).
- A demonstration of these tools running on a Dragonboard 410c
<http://www.96boards.org/products/ce/dragonboard410c/>, an inexpensive
aarch64 development board.

Bio
William Cohen has been a developer of performance tools at Red Hat for
the past decade. He has worked on numerous performance tools in Red Hat
Enterprise Linux and Fedora, including OProfile, PAPI, SystemTap, and
Dyninst.
