[Zope] ZODB performance via direct disk writes

Would there be any performance gain from having ZODB3 access a raw io device instead of using a filesystem, as can be done in FreeBSD for example? Someone at the FreeBSD booth at Linuxworld said it might, while I heard Ted T'so (one of the Linux ext2 developers) say that raw io access does not actually speed things compared to going through the filesystem layer (specifically he mentioned RDBMS). -- Itamar - itamars@ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust?
