As open source software, WordPress is well known for allowing third-party developers to create various extensions and plugins. WooCommerce taps into that further by offering lots of interesting and exciting additions. Whether you want to easily edit aesthetics, sell on Facebook, ramp up email marketing techniques, understand user behavior or quite frankly do anything else, you'll be able to.
For my money though, comparing SaaS and deployed platforms is a bit too big of an ask. Comparing Apples with Apples is a good ambition but by their nature you have two very different types of fruit there. Magento site performance, for example, is almost entirely dependent on how well set up the store is. A good Magento developer can make it sing – but it takes time and expertise…. As a SasS solution the variance between Shopify sites should be much smaller.
Load time is a pretty straightforward indicator of how fast your site is. Simply put, it’s the measure of how long it takes a page (or pages) on your site to fully load.
