what's the speed difference between the old fake oplocks and the new level II oplocks for read-only executables & other read-only files? On my server, around 80% of all files will never change, but the other files can change. What about adding a "will never change"-user/group to smp.conf? e.g. on my server, all files with owner root.root, mode 644 will never change, so there is no need to verify oplocks, file locks & share semantics before allowing access. (or I could add a new group "rdonly", and all files owned by "root.rdonly" will never change) Regards, Manfred
