The latest version is available from http://www.w3.org/pub/WWW/Library/ This is expected to be the last release of Libwww, since we are now moving to the Jigsaw code base, written in Java. Java provides a more powerful platform for experimentation than C, which will accelerate our new protocol experiments this year. This is the version that was used for the HTTP performance paper "Network Performance Effects of HTTP/1.1, CSS1, and PNG" which you can find at http://www.w3.org/pub/WWW/Protocols/HTTP/Performance/Pipeline.html It supports HTTP/1.1 pipelining, smart output buffering and zlib based decompression and has a complete HTTP/1.1 persistent client cache. As we show in the paper, this makes HTTP/1.1 outperform HTTP/1.0 in all the cases that we have tested. In addition to this we have also done some testing on how HTML case-canonicalization affects compression. You can find the study at http://www.w3.org/pub/WWW/Protocols/HTTP/Performance/Compression/HTMLCanon.h tml It shows that lower case HTML tags is better than uppercase and that mixed casing gives the worst result. You can also find a simple "deflater" tool here. Also, we have done some testing on how compression tends to have a good effect on TCP slow start and delayed acknowledgement. You can find this note at http://www.w3.org/pub/WWW/Protocols/HTTP/Performance/Compression/LAN.html As you might have guessed from the URLs above - we keep a performance overview at http://www.w3.org/pub/WWW/Protocols/HTTP/Performance/ Thanks to Markku Savela for the new SGML parser!
