Hi, Hopefully this information is useful: Slow Network Write Speeds via SMB & CIFS <snip> File Transfer Benchmarks: Windows XP to Windows Server (SMB Writing): ~ 25 Mbps Windows XP to Windows Server (SMB Reading): ~ 75 Mbps Windows 7 to Windows Server (SMB2 Writing): ~ 90 Mbps Windows 7 to Windows Server (SMB2 Reading): ~ 90 Mbps <snip> http://social.technet.microsoft.com/Forums/en/winserverfiles/thread/46898c7f-92e0-4c99-98d2-18a7458a7d2d Best regards Joan From: Tal Bar-Or <tbaror@xxxxxxxxx> On Mon, 23 Nov 2009 23:43:53 +0200 Tal Bar-Or wrote: just from first look it seems that your DB server is having some kind file system delay (smb) 4 sec approx, although i saw it also from client side in the system part.

I took a capture from a workstation client and it only seems slow when retrieving the data but once the data is retrieved, manipulating seems normal. There are 3-10 second delays in accessing tables etc. The workstation IP: 192.168.0.13 (windows xp pro sp3) Database Server IP: 192.168.0.3 (windows server 2008 standard) Application Name: Agris (pervasive database) I've completely disabled symantec on both the client and the server and it hasn't made a bit of difference. I'm having a hard time sifting through the capture I took. All I did was have the client login and access a report during the capture. Maybe 20 seconds tops. I've attached the capture file; if anyone can see anything useful, I would appreciate you sharing it. TIA, John ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
