Host 2: 00:30 Hello everyone. Welcome to “On the Net”, where it’s all about your online presence. Thanks for joining us! This podcast is designed to make doing business online easy for web designers, developers, bloggers and online business of every shape and size. Whether you are new to buying web hosting or running a web site, this podcast show will be able to answer your most burning questions. This edition of “On the Net” is all about improving Apache performance. We will offer general performance improvement guidelines along with helpful tips and tricks to help your web server “Be all it can be!” Have you ever gone to a web site or utilized a web-based tool and thought to yourself, “Man, this is so slow I want to scream!”? Well you are not alone. Thankfully, for the diligent web professional, there are some easy tricks you can use to keep your web server from being one of these time-wasting annoyances.
Host 2: 01:18 First let’s talk about some basics. Ultimately, great performance comes down to efficiently using the hardware provided. The single biggest hardware issue affecting webserver performance, as one might guess, is having enough RAM. Of course, you can always buy more RAM, but if not, there are some ways you can take better advantage of the RAM you have. A webserver should never have to exchange live data currently in your RAM with stored data on your hard drive as swapping dramatically increases the latency of each request. As the web server processes web requests, it spawns individual process “children” to handle each request. Each of these children is known as a “Request Worker”, and each child is given its own section of memory to handle the work. In your httpd.conf file, you will find a “MaxRequestWorkers” setting. Here is an easy trick to determine the how many max request workers you should have.
Host 2: 02:11 You want to use as much of the RAM as possible without swapping. To determine the optimal amount, use the task manager of your choice to determine the average size of each webserver process. Divide this in to your total memory. Be sure to leave room for other processes! You can also increase your write buffer size. If you have never heard of a write buffer, a write buffer is a type of data buffer used by your server when the CPU is processing information to be written to memory.
