Wednesday, September 30, 2020 – Queuing – A Deep Dive Into Common Performance Mysteries

As the ongoing COVID-19 pandemic continues to impact our daily lives, we are making our September KWality Talk available online for free.

Location: Online via this Zoom meeting link that will be available closer to the meeting.

Time: Stream will start at approximately 11:55 am. Meeting starts at 12:00 pm. Meeting ends at approximately 1:00 pm.

Speaker: Nicola Gordon and Ioan Matei

Topic: Software performance issues can often be attributed to large or growing resource queues. The primary goal of this presentation will be to enable participants to identify and reduce queuing bottlenecks in their application.

We’ll touch on Little’s Law, show visuals of what this looks like conceptually, and view some graphs that illustrate how queuing manifests as end user response, and CPU usage. By now, our audience will know that us performance engineers are a little obsessed with graphs. But hold onto your seats fellow testers – check out the hockey stick effect and the graphs that solve the mystery – it’ll blow your mind!

Bio: Nicola Gordon is a performance engineer at D2L. Software performance KPIs are her North Star, but check out the trenches on any given day and you’ll find she loves to read a good graph, to tackle a good performance mystery, and to find creative solutions to complex performance challenges. For this presentation, Nicola will be joined by Ioan Matei, her colleague at D2L who is also a performance engineer.
