I want to improve the delay on the server,the mean response time by giving priority to the client that has fastest connection first. If the fastest connection receive priority at the server, they will have good conditions (in the server and in the network) to finish quickly, contributing to minimize the mean response time.I still don't know how to configure the apache to do this scheduling policy. And how the throughput of each client can be known by the apache. Thanks for your advice and answer for my problem.
Allen Pulsifer <[EMAIL PROTECTED]> wrote: Apache already gives priority to the clients with the fastest connection. To user stand why this is so, you need to understand how TCP/IP flow control works and how that interacts with the send(), recv() and select() system calls, and with the network send and receive buffers on the server and the clients. That is not something I'm going to explain though--you might be able to find that information on the www or in a networking textbook. Do you have any reason to believe the "priority" of serving clients is an issue? If so, I assume you have a testbed of some kind? Please describe your setup and what kind of performance you are experiencing. What is the bottleneck? Outgoing network bandwidth? The clients' individual and collective bandwidth? The internet? Server CPU? Server disk throughput? In your setup, is Apache spending resources on slow clients that it could reallocate to faster clients? If so, what is the resource you believe could be reallocated? How do you propose to reallocate this resource and how will that lead to higher performance? In terms of measuring client throughput, if certain clients in your testbed have faster connections, you could start by figuring out their IP addresses, hack Apache to give those IP addresses higher priority, and see if that has any effect on performance. > -----Original Message----- > From: Niko Wilfritz Sianipar Sianipar > [mailto:[EMAIL PROTECTED] > Sent: Friday, June 29, 2007 1:24 AM > To: [email protected] > Subject: Balasan: Re: Apache configuration (throughput of connection) > > > OK, I want to clear my question: > I have a task to improve apache performance by giving the > priority to client that has the fastest connection first.
