How does enabling Keep-Alive make my website faster? Enabling keep-alive makes it possible to use just one TCP/IP connection to retrieve multiple web files (the files your web pages load) at once instead of having to create a connection for every single file. This speeds up the process of retrieving your web files since using one persistent TCP/IP connection instead of using multiple connections will result in faster page load times.
