[Samba] Troubleshooting poor performance with only Windows clients

[Chris Stankevitz]

Hello,

Can you recommend a first step in diagnosing these symptoms:

The following operations are always fast:
- browsing shared with osx/linux client
- moving directories with osx/linux client

The following operations are sometimes absurdly painfully slow:
- browsing shared with windows 7 client
- moving directories with windows 7 client

Wireshark shows:
- When using windows: Lots of ~10 second "high latency" comms with
samba finally responding with "Find Response" and "Create Response,
Error: STATUS_OBJECT_NAME_NOT_FOUND"
- When using windows: lots of requests for folder.gif and folder.jpg
- When using osx: no high latency comms, no responses of type
STATUS_OBJECT_NAME_NOT_FOUND


Thank you,

Chris

PS: I'm running samba 4.1.13 on FreeBSD 9.3 (FreeNAS)
