You'd need more than that: you'd also want to exclude any local processes on the server from accessing the filesystem. I think that would limit the usefulness of such a feature, but, sure, it'd allow some optimizations. In particular, it'd mean you wouldn't have to wait for a commit before closing a file; the client could delay the commit operation till long after the close if desired. Regular v4.0 file delegations also allow that, though. Something like "tar -x" would still be painful, since the file and directory creations would still require waiting for the disk, because otherwise the client has no way to know if those new objects will still be there after a reboot. --b. _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
