30x Faster WP-Super Cache and Site Speed with TMPFS

I haven’t had time to post much the past year, I’m always working! So I wanted to make up for that by publishing an article on a topic that would blow your mind and be something that you could actually start using and really get some benefit out of it. This is one of those articles that the majority of web hosting companies would love to see in paperback, so they could burn it. Now ask yourself, if a webhost makes money based on how much memory, bandwidth, and data used by a customer, what would they not want their customers to do? That’s right, they do not want their customers to learn how to minimize and drastically reduce these moneymakers. They get giddy when you complain about slow-site-speed, or that it takes a long time for your site to load, because they have exactly the right answer- upgrade your memory, bandwidth, and data by purchasing a more expensive plan.

DNS Round Robin Configuration using Rsync over SSH

The goal is to add the HostGator server to be an exact mirror of the static.askapache.com domain, then to add that server as a 2nd A record to my DNS zone. That way half the visitors to the size will be taking up resources and bandwidth on the HostGator server instead of mine.

Round Robin A records in DNS are intended to evenly distribute queries between each host of the same name. Using some tricks straight out of a hackers toolbox we can verify if the distribution is taking place. (It is.)

Speed Up Google Analytics with urchin.js

Update: This article is a bit dated, to get the newest and latest Google Analytics Speed Tips, check out the 3 part update about Hosting, Cookie Domains, and JavaScript Loading and Failproofs

Ever notice that sometimes your sites take a while to load all the way because google’s urchin.js file is taking forever? You may recognize this problem when you see something similar to this in your browsers status bar “Transferring data from google-analytics.com…”

Time To Setup?
4 minutes I got tired of seeing that all the time and so I set up an automated cronjob that runs every 12 hours and downloads the latest version from google, and saves it to my website directory, then I reference /urchin.js instead of http://www.google-analytics.com/urchin.js.. and my site loads a lot faster!
Take a look at the source for this page if you want to see what is going on (look at the bottom)
There are 2 pretty major things that you accomplish by hosting urchin.js locally

You Enable persistant connections
You ensure that the correct 304 Not Modified header is sent back to your site visitors instead of reserving the entire file.

The urch.sh shell script
Create a shell script called urch.sh.. this will be executed every 1/day or 1/wk, whatever you want. The following script removes the local urchin.js, then it wgets the latests version into the local directory.
#!/bin/sh
rm /home/user/websites/askapache.com/z/j/urchin.js
cd /home/user/websites/askapache.com/z/j/
wget http://www.google-analytics.com/urchin.js
chmod 644 /home/user/websites/askapache.com/z/j/urchin.js
cd ${OLDPWD}
exit 0;
Improved shell script
I realized right away that a more modular shell script would be needed.. I admin like 50+ web-sites and it would be stupid to have to type the same block of code 50 times, wget the same file 50 times, etc.. So this version downloads the urchin.js file into a temporary directory, then it copies it OVER the old file for each directory. So 1 GET request…

Caching Tutorial for Webmasters

If you examine the preferences dialog of any modern Web browser (like Internet Explorer, Safari or Mozilla), you’ll probably notice a ‘cache’ setting. This lets you set aside a section of your computer’s hard disk to store representations that you’ve seen, just for you. The browser cache works according to fairly simple rules. It will check to make sure that the representations are fresh, usually once a session (that is, the once in the current invocation of the browser).

Access Control
The restriction of access to network realms. In an Apache context usually the restriction of access to certain URLs.See: Authentication, Authorization, and Access Control

Authoritative Nameserver
A nameserver which has been configured to provide answers for a specific domain, rather than simply getting and caching data about domains from other nameservers.

Authentication
The positive identification of a network entity such as a server, a client, or a user.See: Authentication, Authorization, and Access Control
