I'm using sendfile (on a 2.6.18 kernel) to copy 1M file chunks into a socket. The socket send buffer size is 2MB, and I verify that its empty before making the call. Indeed, 1M chunk is being sent, but from iostat, I can tell that the average request size is around 128KB. Are there any kernel configuration variables that could change that? Help will be appreciated. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
