Good instructor. Tom knows a lot about this material, and has a lot of experience and expertise.
Mar 2021
Trainer is an expert in this field, and provided great explanation.
Dec 2020
It was good to see the instructor showing many things on the command line.
Dec 2020
I liked the paper copy of the course material, and the depth of the coverage of the course matter.
Sep 2020
Keith did great. The course material was good overall.
Sep 2020
I liked it most when Keith added nuggets of knowledge to the course material. His insights into additional techniques and tools were extremely valuable. His blog clearly has great supplemental material for the course, and I hope it becomes a part of the course (BPF kernelshark pressure stall information etc).
Sep 2020
The pace and content of the material is pretty good. I learned a few new commands or tools, but mostly I learned new ways to use the same tools I was already familiar with.
