Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 980 Lines: 29 I've been doing some testing with RH 8.0 on an Ezra 800Mhz machine. Even when lightly loaded select() often returns 3-9 miliseconds slower than the timeout would suggest. I know select is not guaranteed to return with < 10ms accuracy, but with almost no load, shouldn't it at least return with 1ms accuracy on average? I don't remember having this problem on other machines and RH 7.3.... Anyone seen this problem? Compiling a stock 2.4.20 kernel for the Ezra CPU now to see if that helps anything...
