FreeBSD smbfs horribly slow

[Jason Hellenthal]

Is that with the QoS Limit Reservable Bandwidth set to zero ? Or QoS unchecked (disabled) on the source interface of the Win7 machine. By default Win7 limits 10% bandwidth reserved without adjusting the local GPO of the system and sometimes fights with itself to get you the information as quick as you'd like.

Changes here are immediate
