CIFS Auxiliary Parameters

[nubrun]

Hi all,

I just updated my firmware to the FreeNAS 8.0.2 RELEASE P3 and encountered the slow folder browsing as mentioned in this thread: http://forums.freenas.org/showthread.php?5338-Browsing-directories-slow. I have tried to apply the auxiliary parameters mentioned in that thread, but am running into a problem with the GUI. When I add the parameters I keep running into an error with the AIO read write size.
Even if I hit the cancel button at the bottom of the box it won't cancel without those parameters filled in. Does anyone have a fix, or another way to use those parameters. The CIF browsing suddenly is painfully slow.

Thanks,
Nick

Is that a typo or are you running 8.0.2? If you are upgrade to 8.0.4.

Put in values for AIO. Then uncheck it and it will disable AIO. I actually run with AIO on and get better performance, but I never had slow browsing or used 8.0.4.

I'm sorry that was a typo, I am running FreeNAS-8.0.4-RELEASE-p3-x64 (11703) .

Put in values for AIO. Then uncheck it and it will disable AIO. I actually run with AIO on and get better performance, but I never had slow browsing or used 8.0.4.

That is what I am trying to do, and where I am running into trouble. When I open the CIFS settings I see this:
You'll notice that the AIO parameters are populated.

Now just by clicking "cancel" or "ok" this is what I get. I did not change a single setting. Is this a bug, or am I missing something here? Once these warnings pop up about the AIO parameters I cant do anything including adding the additional aux params for CIFS.


Thank you for the help paleoN.

Ok I think I found a bug with this and firefox. I don't run into this problem in internet explorer, but do hit it in firefox.

So using internet explorer I can now add the CIFS aux parameters, but now after I add them I lose the CIFS share to my windows clients (7 and Vista). I am using the following parameters:

socket options = TCP_NODELAY
socket options = IPTOS_LOWDELAY
socket options = SO_KEEPALIVE
socket options = SO_RCVBUF=131072
socket options = SO_SNDBUF=131072
read raw = yes
write raw = yes
max xmit = 65536
getwd cache = yes

And I am seeing the following my my Samba log file:

"[2012/07/09 14:27:54.923177, 0] smbd/trans2.c:844(send_trans2_replies)

"
If I remove the aux parameters everything seems to work (SLOWLY) but work again.

Any help would be much appreciated. This slow file traversing problem just started on friday after several months of working fine, and its really beginning to drive me crazy.

Lose the max xmit = 65536 option. You can try the options out one at a time to see what's causing the problem. I would turn off/on the CIFs service after each change.

You should have a single socket options value. All one line:

Code:

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=131072 SO_SNDBUF=131072 IPTOS_THROUGHPUT

It's fine if the GUI wraps it, but no carriage returns or anything before you paste it in.

I would also try adding:

Code:

write cache size = 131072

That helped to bump my read speeds a bit.
