Each of the test sessions were performed in the manner described
below.
Start the Gnutella client and make sure it gets connections
to 8 other hosts on the network.
Enable statistical logging for incoming and outgoing messages
as well as routing errors.
Let the application work for five minutes to become reasonably
well connected.
Make a search using the keyword divx and note the
number of hits.
Try to start downloading a random sample of the hits. If
download starts it is considered a successful hit, if not an
invalid hit.
After about 30 minutes make an audio search using the artist
keyword Madonna and note the number of hits.
Try to download a random sample in the same way as described
earlier.
After about 45 minutes make a document search using the
keyword nutshell and note the number of hits.
Try downloading a random sample in the same fashion as before.
