We are one of the few who run the addtional web server for Orion NPM. We are preparing to upgrade our installation to ver 9.1 from ver 8.5. One problem we found with the addtional web server was that it ran really really slow. After consulting with your support we had to update the database schema for our custom properties or some such thing. In any case, we did not document this process and we'd like to perform this step when we upgrade so our web performance won't be affected. Can you please post this process as there is very little information supplied in your documentation regarding the addtional web server?
