Two Part SMB issue: shared not showing up in Win & slow transfer to OMV, but not back

Second time playing around with OMV, and have a couple issues:

1: In Windows, the OMV shared folder is not showing up on my Network list. However, if I put the IP into Explorer, it goes right to it. Am I missing turning something on? Have setup SnapRAID with mddfs to create a pooled directory FWIW.

2: Transferred some files from Win 7 to OMV machine, and speed was sustained at ~ 10-12 MB/S. If I transfer the same files back, am getting ~ 100 MB/S. Any ideas on why that would be?

Any thoughts on what to check would be appreciated.

Update: Can transfer files to OMV via FTP at around 30MB/s rate. Around 3x that of using SMB.

Thoughts?
