Samba 4.x package support thread

I've commented out as suggested in this post and now I get 112 MB/s read (almost doble speed than before) and ~100 MB/s writes (a small decrease here) over 1Gbps LAN port with ksmbd.
Probably those settings can be optimized further.
Client is Wn 11 PC.
I've added a post to ksmbd support thread too.
