Hi. I have installed Reporting Services 2005 and found that both Report Server and Report Manager are painfully slow when navigating through folders where reports are stored. I have some previous experience with Reporting Services on other machines and have never so far seen such poor performance. I have no idea what might be causing this behaviour and have not found any answers elsewhere. Thanks for help.

A lot of time anti-virus software causes this with the asp.net processing. Can you rule that out before going into SSRS and IIS itself and the configuration?Ted Krueger Blog on lessthandot.com @onpnt on twitter

I would also rule out the normal steps outlined on BOL here in the last sectionhttp://msdn.microsoft.com/en-us/library/ms345220.aspxTed Krueger Blog on lessthandot.com @onpnt on twitter

Thanks. Will take a look at the anti-virus software as soon as possible (using NOD32 4) and report results.

Hi. I disabled my Antivirus program (NOD), but there was no improvement on the speed of opening folders in Report Manager.

Hi Ted. I finally solved this problem. The disabling of the antivirus program was not enough. I had to make the uninstall/install procedure of the antivirus program and problem magically disappered. You had the answer one year ago :). Thanks.

Hi Tom, It is not necessary to uninstall NOD. You should disable the HTTP/HTTPS scanner in dialog Advanced Setup -> WebAccess Protection -> HTTP, HTTPS. Note that disabling the antivirus scanning and realtime protection does NOT disable HTTP scanning. Therefore your disabling was not enough. Patrick

Thanks, I do think though that realtime protection disabling SHOULD disable HTTP scanning

Thanks, I do think though that realtime protection disabling SHOULD disable HTTP scanning I think they purposely made it so it wouldn't so that when you reboot a server it doesn't get reset the way realtime protection does. That said, they *should* have put it further up the tree and made it obvious. We were having terrible performance because of this and many many hours were wasted. I'll be letting them know.
