| H A D | uipc_sockbuf.c | diff 160875 Tue Aug 01 08:30:26 MDT 2006 rwatson Reimplement socket buffer tear-down in sofree(): as the socket is no longer referenced by other threads (hence our freeing it), we don't need to set the can't send and can't receive flags, wake up the consumers, perform two levels of locking, etc. Implement a fast-path teardown, sbdestroy(), which flushes and releases each socket buffer. A manual dom_dispose of the receive buffer is still required explicitly to GC any in-flight file descriptors, etc, before flushing the buffer. This results in a 9% UP performance improvement and 16% SMP performance improvement on a tight loop of socket();close(); in micro-benchmarking, but will likely also affect CPU-bound macro-benchmark performance. |
