[Владимир Терентьев]

Hi. Try add this to your config in global section.

socket options = SO_KEEPALIVE TCP_NODELAY IPTOS_THROUGHPUT SO_RCVBUF=262140
SO_SNDBUF=262140
max xmit = 262140
stat cache = yes
max stat cache size = 262140
server max protocol = SMB2_10
server min protocol = NT1
client min protocol = NT1
client max protocol = SMB2_10
getwd cache = yes
read raw = yes
write raw = yes
level2 oplocks = yes
locking = yes
getwd cache = yes
use sendfile = yes
large readwrite = yes
