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 ? > > > El Tuesday 05 February 2008 15:44:09 Chris Fanning va escriure: > > > Hi, > > > > > > I'm new on the list but I have had some success using casper on etch. > > > > > > We would like your opinion on a cluster setup that we're think of. > > > The idea is to boot all diskless servers over the network using a > > > single filesystem image. > > > Does that sound like a good idea? > > > > I dont have measures about that, but in the practice creating and using > > live S.O.'s the delay of decompressing the image is not significant.
