110MB/s is suspiciously close to throughput you'd get with a 1 GigE
network. Are you sure your network is end to end 10G? I'll bet this is
not the case, and that some routing or VLAN misconfiguration force
your packets through some 1 Gig link.

First try accessing the Samba server from some other machine (Linux,
windows, whatever) on the same network switch. Modern Linux and Windows
should reach about the same performance with Samba 4.x as NFS.
