I'm no longer that convinced. My observation is that latencies in the 
glfs+unfsd use-case are _much_ higher with 3.0.2rc1 than they were with 
2.0.9. So much higher that the setup is nearly unusable for /home. I 
haven't observed this slow-down with other things on glfs root, though, 
only with unfsd exports. io-cache and write-behind translators seem to 
help a lot, but I'm still weary of using any performance translators at 
the moment, especially with the spurious disconnects I mentioned in a 
separate thread.
