GENERAL INFORMATION ON PERFORMANCE TESTS
|
|
----------------------------------------
|
|
|
|
The following performance tests were based on two file sets: the
|
|
liveCD filesystem from the Ubuntu liveCD (Warty release), and the
|
|
liveCD filesystem from the Damn Small Linux liveCD (release 0.8.4).
|
|
The Ubuntu liveCD filesystem was used to test filesystem performance
|
|
from CDROM and hard disk for Zisofs, Cloop, Squashfs 2.0 and Squashfs2.1.
|
|
CRAMFS filesystem performance could not be tested for this filesystem
|
|
bacause it exceeds the maximum supported size of CRAMFS. To test
|
|
CRAMFS performance against Squashfs, the liveCD filesystem from
|
|
Damn Small Linux was used.
|
|
|
|
NOTE: the usual warnings apply to these results, they are provided for
|
|
illustrative purposes only, and due to different hardware and/or file data, you
|
|
may obtain different results. As such the results are provided "as is" without
|
|
any warranty (either express or implied) and you assume all risks as to their
|
|
quality and accuracy.
