WebCurrently, pipes are only used by kernel-based tcp splicing. Since a pipe contains two file descriptors, the "ulimit-n" value will be increased accordingly. The default value is maxconn/4, which seems to be more than enough for most heavy usages. The splice code dynamically allocates and releases pipes, and can fall back to standard copy, so ... Web17 nov. 2013 · Calling sendfile () or splice () on the underlying FD seems like it would achieve true zero copy on NICs that support-scatter gather DMA. The problem is that when there is scatter-gather DMA support only a pointer to the buffer and the length is written to a NIC when the splice/sendfile calls return. The NIC then asynchronously writes the data ...
