Postoffice Poor Performance on Windows 2012 R2

Hello,
i have compare following POA Performance:
1. Groupwise 2014 R2 on SLES/OES11 with EXT3 Filesystem
Groupwise Client Attachment open PDF 21 MB until 2-3 sec.
2. Groupwise 2014 R2 on Windows 2012 R2 with NTFS Filesystem
Groupwise Client Attachment open PDF 21 MB until 13 - 19 sec.
Both System running on Vmware 6.X with lokal Attached Disk System(Raid 5). No Virus Scanner or any other Software running on Windows.

In Windows i see, only 3,8 MB/s Ethernet Traffic until the Attachment is download from POA.


Have anybody tips to speed up that poa performance on Windows.

Regards Andreas

That is a rather extream slow, that makes me think it is something
other than poa config as I am assuming these tests are on low
utilization systems.

How is memory and CPU utilization on the system at the time of your
tests?
Does opening the attachment a second time come much faster?
If you copy a similar size file on the server to/from the different
volumes/drives, how does that time compare?
Copying such test file off of each server? For the OES box could mount
that volume either as an NCP, CIFS, or SAMBA. Or just use WinSCP.

On your Windows server, do you at least have an AntiVirus to protect
the OS? Just making sure it is excluded from the GroupWise data.

It would be interesting to compare packet captures of the two tests to
see if there is a networking issue that is getting in the way. We've
been building networks with enough smarts to try and get the packets
though that sometimes a bad config or failure gets unnoticed because
the packets are getting through even though they are having a hard
(slow) time doing so. Rather like Iraq's military network in the gulf
war when it kept working despite all the bombing attempts to knock it
down, parts were blown away but the packets still managed to get where
they were needed for the most part.

Re: Postoffice Poor Performance on Windows 2012 R2

Both Groupwise Server running von Vmware 6.X on similar Server with local Disk Space.
SLES / OES 11 Server
Vmware CPU = 2 x 2, Memory 12 GB(6Reserved) 50 GB VMDK and 300 GB VMDK Harddisk both in Eager Zeroed Mode, VMXNET 3 Networkdriver 1 GB Switch Connection. No Virus Software on it.
Windows 2012 R2 Server
Vmware CPU = 1 x 2, Memory 12 GB(Full Reserved) 75 GB VMDK and 100 GB VMDK Harddisk both in Eager Zeroed Mode, VMXNET 3 Networkdriver 1 GB Switch Connetion. No Virus Software on it.

Groupwise 2014 R2 Client: First Try to save the attachment of 21 MB PDF File neat 13 sec, the second time is only 1 sec. The second time i allway fast, Gropwise Client have allready dowload this file in local disk.

There not network problem exist.
- If i copy the Groupwise install zip (1 GB Data) file form the Groupwise Windows Server Drive G: on my local virtual Windows 7 Workstation in 10 sec. With a datatransfer up to 115 MB/Sec. ( SMB Share )
- If i copy the 21 MB Zip PDF File from the Groupwise Windows Server Drive G: on my local virtual Windows 7 Workstation i can not mesaure, on done under a sec.

It nead only 13 sec with the Groupwise Client !. The same Client can to the same File on SLES 11 / OES 11 Groupwise server in 3 sec.

In my mind i have only a problem with the poa agent on Windwose Server 2012 R2.
I have the same problem in our customer on two different datacenter. We have one datacenter for testing and one datcenter for production. On different Hardware in different location.

Re: Postoffice Poor Performance on Windows 2012 R2

Hello, have added following regedit switches on Windows 2012 R2 to tune TCP IP.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
{Interface GUID}* * {Interface GUID} is different for every system.
TcpNoDelay = 1
TcpAckFrequency =1

It speed up a little bit, now i can open a 21 MB PDF File in 11 sec, in compare to SLES 11 / OES 11 in under 3 sec. There is no much step forward.

I'm curious if you see better results by disabling LSO/LSO2 and offload options in the network card properties of that Windows server.

Hi

Further to what has been suggested above, ensure that "Offline Files & Folders" is disabled.

Not necessarily, try that second on a separate user system as that also
tests that server side caching is helping out, which then starts pointing
toward a possible datastore access speed bump.
The second system can be logged into as the same account, or if the
attachment was sent to both users as one message. Though the pathes the
pulling of the attachment might just be different enough that testing
both might be warrented given we haven't found the root cause yet.

Re: Postoffice Poor Performance on Windows 2012 R2

Hi,

Just some further things to try... disable indexing on the Windows server file system and ensure that DEP is disabled (set to essential Windows programs and services only).

Please let us know how it goes.

Cheers,
Laura Buckley

Re: Postoffice Poor Performance on Windows 2012 R2

Hello,
the speed test on many diff workstation with the same account or other account are the same, with the same file size.

I have try to switch of LSO to.
Default: adapter-dependent
Recommended: disable (both in network adapter properties and in the TCP/IP stack at the OS level)
Disable-NetAdapterLso -Name * (disable LSO for all visible network adapters)
Enable-NetAdapterLso -Name * (to enable LSO for both IPv4 and IPv6 on all network adapters, not recommended)
Get-NetAdapterLso -Name * (get a list of network adapters that support LSO)

No better performance is the result.

Re: Postoffice Poor Performance on Windows 2012 R2

Hi Laura,

DEP is disabled.
Indexing on the Groupwise drive is off.
There are no Shadow Snapshot used on the Lauwerk.
Nevertheless, thanks for the tips.
I have a Novell Call opened and already received a bug number. I hope that can help me quickly developing here.

GroupWise customers who want to use the new SSO via Kerberos to the AD, that's a problem. Here, since the Post Office must be installed on a Windows server. Since I have again carried out a migration from Exchange to GroupWise last year that customers are waiting for this new feature. But at the time I am with this Performace not satisfied compared to SLES.

Did you ever find out what was causing this, or find a solution?
