Network performance
-
Tuesday, March 10, 2009 9:52 AMI have installed windows 2008 sbs. On the server is one program which is used by 5 users. At the start this program works ok. But after few days this program works very slow. Like 10 times slower. I noticed that when only one person works on this program it works ok, but when there are two of them it slow down drasticly.
I don't know why this happend after few days. I did turn off firewall and antivirus program, but no changes.
Can someone help me with this?

Wednesday, March 11, 2009 6:40 AMWhat you have mentioned sounds like Oplock issue, but it only affect with SMB or SMB1 protocol. It doesn't affect SMB2. Please read more about OPlocks in below article,
http://support.microsoft.com/kb/296264
+ Can you please share details about client version - if they are 2000 or XP, they will definitely use SMB1. If clients are vista, this article doesn't apply to this scenario.
+ we are dealing with 2000 or XP clinets, please use below registry keys to disable OPlocks from client end rather than disabling from server end,HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\OplocksDisabled REG_DWORD 0 or 1
Hope this helps. -
Wednesday, March 11, 2009 3:19 PMhi there,
i would like to know what is the program,
is it a win32 program ,your custom application ?, if this is your custom application then you would need to explain the architecture of the app even before digging with windows 2008 OS .
As of now there is no file lock / opslock which i would suspect, opslock is a feature which is only specific when accesisng file over a network, then file operations are converted into network requests.
so please confirm and tweak the opslock only if your application is dealing with file related activity.
