Hello,

I using the DNN, as host, now I have 653 portals (sites), I have 2 servers, one IIS, and second SQL 2005, now my all users have problem, sites works very slow, so I thing you understand, what I have. Please, advise me, how can I deside this problem.

Sorry, IIS and SQL, servers are prety good, X64, 4 - processors, and about 4gb of RAM.

Firstly, thanks a lot for so quick replay. I realy appreciated.The sitution is as a follow:

On IIS server i have all files of portals and  a virtual server allias.You can try it www.intway.ms

Second server is SQL 2005 server with database and  datafiles on the RAID massive. Firstly, the problem was with connection between IIS and SQL. I remade the internal connection between servers by the internal network. This a little bit improve site loading.Next, i analize the working procedures on SQL and find out that the procedure GetAllTabs works to slow. I took the sourse code of the view and put it into the procedure. That also a little bit improve site loading, also I make the improvens on IIS like cash, timeout and so on. But now it works a very slow. If you need more detailes, please, let me know.

Thanks a lot, Igor.
