In-Reply-To: <1110568180.17740.69.camel@localhost.localdomain> Message-ID: References: <1110568180.17740.69.camel@localhost.localdomain> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1531 Lines: 44 Dear Alan, I am positive. I can setsockopt, and then, getsockopt returns the value that I requested. Stevens very clearly states that SO_RCVLOWAT has a direct impact on select() and I assumed that this would be the case for Linux. What is the rationale for not complying with that ? Is it the micromanagement of select() that you dislike ? Isn't a significant reduction in the amount of read operations a real gain in high speed networking ?
