I am running a few VirtualBox VMs with 9.1 on my OpenIndiana server and = I noticed that make buildworld seem to take much longer=20 when the clients mount /usr/src and /usr/obj over NFS V4 than when they = use V3. Unfortunately I have to use V4 as a buildworld on V3 hangs the server = completely... I noticed the number of PUTFH/GETATTR/GETFH calls in in the order of a = few thousand per second and if I snoop the traffic I see the same filenames appear over and over = again. It looks like the client is not caching anything at all and using a = server request everytime. I use the default mount options: 192.168.178.24:/data/ports on /usr/ports (nfs, nfsv4acls) 192.168.178.24:/data/src on /usr/src (nfs, nfsv4acls) 192.168.178.24:/data/obj on /usr/obj (nfs, nfsv4acls) Any ideas, Paul
