FastCGI: Persistent Applications for Your Web Server
My example script doesn't tackle many of the tasks at which FastCGI excels: persistent database connections, format translation (e.g., SGML to HTML) or providing common HTML page headers and footers. At the site I manage, I use FastCGI to do all these things and more.
I've found that a FastCGI application can perform its duties, including multiple SQL queries, and deliver a page on the fly only slightly slower than the server can deliver static documents. On a 10Mbps LAN connection the speed difference is perceptible, but just barely, and only if I'm looking for it. Over a 128Kbps or slower connection, I notice no difference.
I still use CGI to perform simple, infrequently needed tasks. A CGI script doesn't hog system resources for very long. For complex, frequently invoked tasks, FastCGI provides a great combination of flexibility and speed.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
