In "normal" mode, Tomcat reads the file into its own memory buffer, optionally compresses it, and then writes it out again to the socket. In "sendFile" mode, Tomcat tells the O/S to transfer the contents of the file directly to the socket (bypassing reading it in to Tomcat memory). On a modern O/S, this allows the O/S to transfer data using kernel memory only, instead of copying the kernel memory to program memory first (which has a significant cost on high-volume servers). > It looks like my solution is to simply disable this option, but I was > curious about why this is the case.
