sendfile() only works for plain HTTP. For technical reasons it does not work for HTTPS (). These days majority of services use HTTPS. Therefore the usefulness of sendfile() patch is minimal. () It is possible to use sendfile() for TLS connections, but the feature requires a Kernel module that provides kTLS offloading feature, https://www.kernel.org/doc/html/latest/networking/tls-offload.html . In user space it requires OpenSSL 3.0.0 with kTLS support. 3.0.0 is currently under development.
