fast encrypted NFS but slow regular NFS
We are using nfs to export the homedirs to all our users on the network here. We export the nfs-shares on the server to localhost, mount the shares on the clients from localhost, and make an ssh-tunnel from client to server to connect the two ports together. This way we have encrypted nfs, and this works like a charm, as well as very fast.
But on my machine I would temporarily like to import the homedirs without root_squashing so I can make backups of everybody's files. Since this is only temporary I use just a regular NFS export, not the encrypted one. But this share is SLOW! I mean like 20 kbps. Anybody any ideas how I can improve the speed? I don't want to change the entire server-configuration just to run one backup (our backupserver is down for the moment). I use the options ro,no_root_squash,sync for the export.
