I guess we are running the same setup as you do, Orion on the same server as the database.
We upgraded from 7.8.5. to 8.0 in december and to 8.0.1 as soo as it was available. Our main reason for upgrading was Custom MIB and Netflow, where Custom MIB was a nice-have and Netflow a must have.
A month later and I still have problems. I've abandoned Custom MIB altogether, it just isn't presented the way I need it and I'm still using an open source app to graph Custom MIB.
The quest to gather Netflow statistics has led me to realize I have to move the 37gb Orion database to a seperate server. When I activate netflow from any source Orion just freezes and sometimes stops gathering overall statistics. Until I get the other SQL running Netflow just isn't working for me.
Not many good news, but I could be a worst case.
