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!

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;

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 …
