Yes, it's exactly what I needed, thanks.

It seems that we use a terribly inefficient way to write out directories, 
with no buffering at all. It also seems that you have a large directory on 
a remote network store mounted synchronously, which forces a round trip 
to write each directory entry (no local buffering in the OS).

First of all, you could try enabling the "async" option on your NFS mount 
to see if that helps.

I'll work on a fix, but it's not trivial to get right, so it might take me 
a while.

Cheers, Chris.
