Samba-3.0.28 calls set_filetime() from real_write_file(), which 3.0.8 isn't
doing.
set_filetime -> utimes -> nfs SETATTR (in my case)
After removing that bit from real_write_file, I get exactly the same
performance I had before. Now, I realise this has probably been put there
for a reason...
Stuck now, any advice on the matter appreciated
It was put there to properly support the so-called sticky
write time feature that for example Excel depends upon.
Stefan Metzmacher has written a patch that needs to be
merged that avoids those utime calls by putting the relevant
data into locking.tdb. We need to take some time to shape up
that patch a bit and merge upstream though.
