At our April 2020 meeting Renée Stephen gave the Vancouver Drupal maintenance support plans User Group (VanDUG) an encore of her Pacific Northwest Drupal maintenance support plans Summit (PNWDS) presentation: No more performance anxiety! The presentation walked us through the formal process of server load testing.
Renée’s current gig as Technical Consultant at Acquia gives has given her lots of experience on the subject and she knows how to present. It’s always a pleasure when someone deeply steeped in domain knowledge gives a great presentation.
I can’t begin to summarize the entire presentation. Renée’s slide-deck is available for download at the presentation description on the PNWDS website: No more performance anxiety: get your Drupal maintenance support plans site tuned and ready to take the stage!

Here are the take-aways that surprised me:
The standard definition of load testing is backend server oriented and does not include front-end performance issues. For example, large hero images or JavaScript widget rendering. While these are important they are not part of this discipline and usually require different tool sets.
You’ll want at least 2 days, possibly more, to familiarize yourself with jMeter.
I was also reminded of how much server and tool knowledge is required if you’re the one doing the remediation. No single detail is exceedingly complicated but each technology in the stack has its particulars, tools, and metics.
Here are the tools Renée mentioned in her presentation:
Profiling Toolkit
Blazemeter Recorder
Postman
HAR
jMeter
Drupal & Static Analysis
Blazemeter / jMeter
Apachebench (ab)
New Relic / TraceView / XHProf
WebPage Test
Chrome Inspector
Server logs and stats
varnishstat / varnishlog
Redis monitor / memcached-tool
Drupal maintenance support plans Devel module WebProfiler
She also made a repo of her jMeter example files available at https://github.com/reinette/loadtest
A big thank you to Renée for presenting. I missed the presentation at PNWDS and was happy for the second change to see it.
