While we’ve achieved dramatic improvements in the performance of websites built and hosted on Wix, we continue to investigate new capabilities and enhancements to our platform to further improve site speed. Every feature developed at Wix is tested to ensure that it doesn’t hurt the performance of existing sites. This is accomplished by conducting automated acceptance tests that compare the performance of a wide variety of sites before and after the change. If any performance degradation is detected, the deployment of the new feature is blocked until this is fixed. In addition, the performance of every site session is monitored (anonymously), in real time. This lets us verify that your visitors experience the best possible site speed.
