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 [...]

cURL is an application that can be used to retrieve any Internet file that uses the standard URL format — http://, ftp://, gopher://, etc. Its power and flexibility can be added to applications by using the libcurl library, whose API can be accessed easily using most of the commonly used scripting and programming languages.

In todays highly competitive e-commerce marketplace, the performance of a web-site plays a key role in attracting new and retaining current clients. New technologies are being developed to help speed up the delivery of content to customers while still allowing companies to get their message across using rich, graphical content.

A few years ago, I wrote an article ablout how to best set up Web server cache-control messages to take advantage of this free form of content distribution. Until now, it has only existed as a PDF file.
Last night, I sent a copy to Kevin Burton of TailRank in response to some of his recent [...]

At my job, I get involved in trying to solve a lot of hairball problems that seem obscure and bizarre. It’s the nature of what I do.
Over the last 3 weeks, some issues that we have been investigating as independent performance-related trends merged into a single meta-issue. I can’t go into the details right now, [...]

DNS has been a great hidden mystery to most people who use the Internet regularly. As a Web performance analyst, I see the effects of poorly deployed or improperly maintained DNS services.
Business 2.0 brings this to the rest of you. While sounding a little apocalyptic, it does highlight a problem that those of us who [...]

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 [...]

Now, I never even heard about this Comcast outage until this morning. [here]
One reason that I likely didn’t notice it is that I run my own caching name servers on my home network. I do this because I have never trusted any provider’s overworked name servers (goes back to the history of the industry I [...]

The folks at Port80 Software have released Version 3.0 of httpZip, their compression and caching application for IIS servers.

Congrats!
