Hello,

Just for curiosity, what about version 4.5.8? This is the version
included in current Debian stable (stretch).

If you are going to upgrade, you might as well go for the highest
version you can, this will probably mean using Louis's packages.

Samba is a rapidly changing program, a new minor version is released
every 6 months (approx) and the changes are significant.

4.7.0 is due out at in September and there are going to be a lot of
improvements in it.

I've upgraded to 4.5.12 : absolutely no difference. smbd consumes 100%
of CPU when writing or reading a paltry 100 MB/s. I'll try 4.6.x but
I'm desperate. I'll probably need to replace the server altogether (and
it's a PITA because it's 600 km away).
