Client has to wait long for its answer after many queries served, although server is still fast

Dear all, I have the following setup: 1. A server written in C++: It waits for a request on a given port (using accept), reads whatever is sent (using read), computes an answer string, sends it back (using write), then closes the connection (using close). 2. A client written in PHP: It opens the connection (using fsockopen), sends the request string (using fwrite), reads the data (using fgets), then closes the connection (using fclose). Queries come in at an average rate of about one query per second. The server needs a few milliseconds to compute the answer string The who

A Trend Towards Lower Software Maintenance Budgets?

Software maintenance is an important part of the software development activity, but it is also the less discussed. A recent poll seems to show that the part of maintenance in software development budget is going down. Why? Question: what percentage of your software development budget is devoted to maintenance. Maintenance is defined as process of correcting, enhancing and optimising deployed software. 25% or less of the budget ...........37% 26% to 50% of the budget ............27% 51% to 75% of the budget ............24% more than 75% of the budget .........12% Number of part

The Relative Importance of Web Development

If you follow the evolution of software development on Internet, you may have the impression that every new development is Web based and that the main areas of concern are whether you should develop new application with Ruby on Rail or if you should choose Flash rather than Ajax for the interface. However, if you ask developers, you may find that the Web is not as ubiquitous in their work as you may think. Even if 66% of the participants develop the majority of their new applications with a browser as the interface, there is still a large portion of developers that are working today

Survey: More Offshoring than Outsourcing in Software Development?

Outsourcing is often closely related to offshoring in software development, but you can outsource onshore and you can create offshore subsidiaries. This seems to be the current trend for large occidental organisation that want to profit for lower costs in countries like India, but maintain a high control on the process. However, developers in Europe or North America feel no differences if their Asian "competitor" work for a subsidiary or for another organisation. A recent poll from Methods & Tools wanted to know if applications are developed exclusively inside organisations or if outso

How do i avoid packet segmentation?

Hi, I'm writing a program that sends 1500 bytes of data at once, from the client to the server. However, the packet is broken down into 3 different segments of 500 each before getting to the server. This is detrimental to the program i'm writing as I need the server to receive the entire 1500 bytes at once. How do I avoid this segmentation. Is it a linux setting which I can change or is it a TCP setting? either way, what can I do? I'm sending the packets using the C send() function.
