AFIAK "lofi" operates on the block device level while "SquashFS" does the stuff on the filesystem level... ... maybe I'm wrong... but my feeling says that "SquashFS" has better options for optimisations, e.g. compress rarely used stuff with a high compression level (requiring more CPU time) and the often used stuff with a lower level... or a global block-sort system to put similar blocks together to obtain better compression leveles etc. ... ... and "SquashFS" would not require an extra filesystem, e.g. it replaces both "ufs" and "lofi" in a smaller, more compact kernel module. ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
