You are welcome,
I have tested the plain filesystem in a standalone computer,
that is an AMD Athlon 64 X2 6000+, a powerful processor, 2 GB of RAM and a
disc sata II at 7200 rpm,
Debian live is lenny with squashfs v3.2, does not use lzma.
in that machine squashfs outperforms the plain filesystem in 10% better
perfomance for squashfs,
Someone has measured network performance ?
