17 Mar 2009For a number of years, I have owned three very popular domain names: WebPerformance.org, WebCaching.org, and WebCompression.org. Last night, after many days of consideration, I stopped pointing them at their own distinct Web space and pointed them at this blog.
This is not a bad or evil thing, considering that for at least 18 months, the [...]

6 Aug 2008So, the last post I put up simply stated that I had failed in installing Worpress 2.6 on my own server. The permalinks were messed up and it looked a lot like an issue that a lot of people were having.
But, the catch was: the problem persisted when I tried to use Wordpress 2.5.1. Hmmm…wonder [...]

6 Jun 2007Dear Apache Software Foundation, and the developers of the Apache Web server:
I would like to thank you for developing a great product. I rely on it daily to host my own sites, and a large number of people on the Internet seem to share my love of this software.
However, it appears that you seem to [...]

16 Jan 2007It’s always funny when somewhat tech-savvy folks purposely make their bandwidth bills higher than they need to be.

Port80 Software’s Compression Checker gives us some idea how much bandwidth Mr. [...]
Port80 Software is reporting that in their survey of Fortune 1000 Web sites, IIS 6.0 has overtaken Apache as the Web server platform of choice. [here]
My two-cents: I respect the Port80 Software team greatly and love their maniacal devotion to ensuring that IIS users actually make use of the HTTP compression and caching that can [...]
This paper is an extension of the work done for another article that highlighted the performance benefits of retrieving uncompressed and compressed objects directly from the origin server. I wanted to add a proxy server into the stream and determine if proxy servers helped improve the performance of object downloads, and by how much.
Using the [...]
How much improvement can you see with compression? The difference in measured download times on a very lightly loaded server indicates that the time to download the Base Page (the initial HTML file) improved by between 1.3 and 1.6 seconds across a very slow connection when compression was used.
Base Page Performance
There is a slightly slower [...]
The last time I attempted to compile mod_gzip into Apache, I found that the instructions for doing so were not documented clearly on the project page. After a couple of failed attempts, I finally found the instructions buried at the end of the ChangeLog document.
I present the instructions here to preserve your sanity.
Before you can [...]
NOTE: This hack is only relevant to Apache 2.0.44 or lower. Starting with Apache 2.0.45, the server contains the DeflateCompressionLevel directive, which allows for user-configured compression levels in the httpd.conf file.
One of the complaints leveled against mod_deflate for Apache 2.0.44 and below has been the lower compression ratio that it produces when compared to mod_gzip [...]
Blog Statistics Analysis – What do your visitors actually read?

14 Sep 2008Steven Hodson of WinExtra posted a screenshot of his personal Wordpress stats for the last three years last night. I then posted my stats for a similar period of time, and Steven shot back with some question about traffic, and the ebbs and flows of readers.
Being the stats nut that I am, I went and [...]
