Overview

For a good overview of current WWW technology, Serverwatch is a terrific resource. It is intended to aid Webmasters in their search for the right Web technology, including supporting tools and products.

Benchmarks

Below are links to Web server benchmarking utilities and to other sources of information for benchmarking results.
WebStone
Considered the standard benchmarking tool for Web servers. It was heavily influenced by the design of LADDIS, an NFS benchmarking tool.

WebCompare
Provides in-depth information on server software for the World Wide Web. Included are pointer to other benchmarking efforts.
Zeus performance
The makers of the perhaps the best performing commercial Web server have results supporting their claim. Included are discussions about why they implemented their own benchmarking client rather than using WebStone.

Protocols

Listed here are reference documentation to protocols which we intend to fully implement into the Web server.
HTTP/1.0
The current standard protocol of Web servers and clients.
HTTP/1.1
The next generation of HTTP, supporting persistent connections and other goodies.

Web Servers

These are the homepages of the servers we use in our test-suite, as well as other servers, which we intend include in our suite in future benchmarking tests.
NCSA HTTPd
One of the original HTTP servers.
