FreeBSD smbfs horribly slow

[Mark Saad]

Mario
  Can you share more about your setup .
What filesystem is the samba share exported from . What mount options on the filesystem level do you use ?

What version of samba , was it from ports or a package ?

On the samba level can you tell us about your config ? Have you tried any of the tuning from 
https://calomel.org/samba_optimize.html

Did you change any sysctls ? What did you set ?

Lastly what's the hardware like ; CPU, nic type , ram , etc
