The Speed Demon reference site was created by Mindsize as a testbed for performance optimization techniques and new technologies. We set out to create the fastest WooCommerce-powered store that we could using commodity hardware with very little customization. On this reference site, we’re using Serverpilot with Digital Ocean, some Redis, a little bit of WP Rocket and a whole bunch of Imagify. That’s not to say there isn’t more than one right way to do this, this is just the stack we chose to use for this particular test.
