I think I found it.
Samba-3.0.28 calls set_filetime() from real_write_file(), which 3.0.8 isn't
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
