BigCommerce vs WooCommerce Performance
The performance of an online store is essential to customer mom database experience. If your website is performing poorly, customers won’t be able to find you, won’t stick around to complete the checkout process, and will ultimately go to your competition because your site is slow. Data shows that as page speed decreases, the likelihood of users abandoning the page increases significantly .
Loading time
Visitors want websites to load fast, and if yours doesn't, you can kiss traffic goodbye. Search engines also provide good user experience, so they will only recommend sites that load quickly. If your site speed suffers for an extended period of time, you will lose rankings in favor of sites that provide the same information and deliver it promptly.

BigCommerce has an average loading time of 2.2 seconds, in line with industry expectations. WooCommerce, on the other hand, has an average loading time of 4.3 seconds. The difference in speed could be due to a few factors such as the hosting platform used and the plugins installed. With a Managed WooCommerce , the average loading speed was 1.93 seconds.
Page Speed
