Finding MySQL Scaling Problems Using perf (opens in new tab)

The thing I wish I’d learned while still a DBA is how to use perf. Conversely after moving to a developer role, getting access to real external client workloads to get a perf recording directly is rare. To bridge this gap, I hope to encourage a bit of perf usage to help DBAs report bugs/feature requests in more detail to MySQL developers, who can then serve your needs better.
