OpenSSH NoPty patch
Hey everyone,

performance problem on bridgehead DC
...C.
I have 19 DC (Debian Stretch / Samba 4.6.7 from Tranquil.it repo) and they all synchronized on a main bridgehead DC.
This performance problem first appears when the bridgehead DC was on Debian Jessie and kernel was updated with meltdown/spectre patch from Debian (3.16.51-3+deb8u1)
I added "nopti" option to grub boot to resolve the performance problem.
Last night, I upgrade this Bridgehead DC from Jessie -> Stretch (samba package 4.6.7 from Tranquil.it is the same for Jessie and Stretch), I also keep "nopti" option but problem is back again.
There is 2 processes eating lo...
