Summary of Test Runs with Automatic Generated Xplots

The following data is a compilation of tcpdumps taken with different client/server combinations. Each testrun generates three data sets: HTTP/1.0, HTTP/1.1, and HTTP pipelining.

Naming Scheme

The names of the runs are named as follows: 
    <SERVER> - <BANDWIDTH> - <LATENCY> - <HTTP CLIENT VERSION>
SERVER
J stands for jigsaw and A stands for Apache. The number is for us to keep track of which version of each we are trying.
BANDWIDTH
H stands for high (for example a LAN) and L stands for low, for example PPP
LATENCY
H stands for high latency, for example WAN) and L stands for low, for example LAN
HTTP CLIENT VERSION
These are the suffixes used: http-10 is plain HTTP/1.0, http-11 is without pipelining, http-11-pl is with pipelining, and http-11-pl-zip is HTTP/1.1 with pipelining and deflate content encoding.
Each combination is run 5 times and each run consists of a first time retrieval followed by a cache validation. That is in all 10 times pr combination. We use this for naming the results: As an example, take the following name: 
    A1-LH-http-11
