Are you running the polling engine / web server / and SQL server on the same box?

You need more memory... at least 2 gig.

I am running the same server spec as you have, but 4 times the RAM.
SQL uses 1.7Gb alone. IIS uses 150Mb, NetPerfMon uses 130Mb.

Web site performance is good, loading 1300x1000 pixel network map
in about 3-5 seconds. Homepage with ~ 500 nodes about 1-2 seconds.

I´ve also got some really serious performance problems. I´ve moved to a 2Ghz machine with 640MB RAM monitoring only 100 elements right now. The problem seems to be that dllhost.exe (IIS that is) is running wild (nearly 100% CPU) when loading webpages. I´ve seen this exact behaviour at the first machine we installed it on.

One thing that I recently discovered with the new version:

I was having serious performance problems with my machine since upgrading to 7.0. They were not related in any way to some of the things mentioned on this board in previous posts (i.e. lsass etc.) What I found is that for some reason Mcaffe antivirus was slowing the page loads way down because it was trying to scan every single object as it loaded. I am not talking about the AV on the client machine. The problem was the AV on the server. I set up AV to exclude scanning certain directories relating to Solarwinds. Ever since then V7 screams. If you want to check out if this could be your problem simply stop your AV services on the web server and then make a client connection and see if your response time improves. If it does improve then setup you AV to exlude the solarwinds and website directories. If it doesn't improve then I guess it's back to the drawing board. Just a helpful tip.

Thanks,
Dimo

My server has no virus protection - only MSDE, IIS and Orion 7.
I´ve tried to tune performance but it still is soooo slow. It can take up to a minute to load a map... DLLhost.exe is still the bad guy.

More RAM. "640Mb is not enough for anyone"

If you are running SQL on this server as well, you definitely need more RAM.
At least a Gig, preferably 2.

Here are the system specs on my server which runs reasonably well, although it is somewhat slower than V6.4

Diagnostics suggestions:

There are a few things you can check - memory has already been suggested, and this is key. Depending on what else you are running off SQL, you can limit the amount of memory that SQL uses to prevent it sucking up the entire stack. Another perfomance checkpoint is disks - do you have your disks in the recommended config for SQL enterprise (3 physical, 1=system/programs, 2=SQL logs, 3=SQL DBs)? Something as simple as installing an extra HDD & moving the pagefile onto it might help. Use perfmon to check your disk queues.

another thing that made a huge difference for me:
I wrote a batch file to delete the temporary files on the web server(s) and used scheduler to run it every 2 hours. I have a very deep map with lots of objects (16 6500s fully populated with every port on a map page as an object). my response times are great...SQL response time is VERY important as well.

see attached and change .txt to .bat to run.
