SUSE Labs Conference 2018 - Benchmarking Object Storage
Channel: SUSE Labs
Date: 2018-09-17

During this presentation I'll describe an opensource set of tools I've written
and use for benchmarking cloud8 swift and ses object storage.

But just running a benchmarking tool that reports IOPS is never really enough
and these tools go deeper to allow one to report details about individual
operations and their timings.  It is also just as important to understand what
the benchmark results mean such as whether or not there is a system/network
problem. By correlating this data with tools like collectl (if they report disk
timings) one can sometimes spot a misbehaving disk.

Perhaps there is a bug in the object storage code itself? By examing individual
operational latenties, several problems were found that file system developers
had no idea even existed.

So in addition to presenting some real-world numbers, I'll also be talking about
how to interpret the results and what they might mean as well as the methodolgy
to assure the results be both meaningful and repeatable.
