We released HTTP-FUSE KNOPPIX 4.0.
http://unit.aist.go.jp/itri/knoppix/.../index-en.html

HTTP-FUSE-KNOPPIX-4.0 is only 5MB CD image and enables us to use full contents of DVD KNOPPIX 4.0.
We don't need to download 3.8GB iso image at one time and burn DVD.

Following figures (Figure1 and 2) show difference of normal DVD-KNOPPIX and HTTP-FUSE KNOPPIX.

# Unfortunately HTTP servers for HTTP-FUSE-KNOPPIX-4.0 exist in Japan.
# The long network delay from US or EU makes boot slow.
# HTTP-FUSE-KNOPPIX can connect P2P "coral" proxy. We hope P2P Proxy works well.

We estimate the performance. If there is no network delay, HTTP-FUSE KNOPPIX boot is faster than DVD KNOPPIX.
Long network delay (We assumed 200msec between US&EU and Japan) makes slow boot.
To hide the network delay we add DownloadAhead function(DL-FULL and DL-2500) which prefetches necessary data beforehand.
The results of boot time, amount of download data, and throughput are following graphs.

BOOT TIME of HTTP FUSE KNOPPIX (DVD-BOOT TIME 295sec)
at NO DELAY
# DL-FULL 97sec
# DL-2500 98sec
# NON-DL 113sec

at 200msec DELAY
# DL-FULL 437sec
# DL-2500 644sec
# NON-DL 1413sec
