Footnote 1

These measurements were performed using max 4 (default) simultaneous connections and HTTP/1.0 Keep-Alive headers. The Netscape HTTP client implementation uses the HTTP/1.0 Keep-Alive mechanism to allow for multiple HTTP messages to be transmitted on the same TCP connection. It therefore used 8 connections compared to 42 for the libwww HTTP/1.0 implementation, in which this feature was disabled.
