samba - Dec 2014 - Troubleshooting poor performance with only Windows clients

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)

I put smbd info "full log" mode.  Then I tail -f the log and watched
while I browsed on windows.  When windows is absurdly slow, smbd is
showing smbd_dirptr_get_entry entries for every file in the tree.
This is a lot of files in my case.  I assume windows is
opening/downloading/peeking_at every file in the tree; however, I do
not know why.  The following two steps do not help:

- veto files = /Thumbs.db/
- From windows 7 explorer: "Always show icons, never thumbnails"

So I am left to wonder WTF windows is doing.

Maybe it updates its search index, or does a virus-scan.
