Do you mean by CPU a virtual CPU (i.e., one process)? If so, 10 users per process is very good. That seems to be what you are describing. If so, that's very good. I typically aim at 3 users per process (in a highly transactional system that does a lot of reports that need crunching).


>>>>On one server, by example, we have sometimes between 20 and 30 users (or more) running in a 2X environment. 2.8Ghz CPU, 16Gb RAM, SSD, 8 core CPU. Users are running various reports, drawing charts, looking at financial statements, PDF files, looking at real-time news feeds, displaying real-time stock market data in various types of reports and various real-time updating charts. An average user may have anywhere between 10 to 50 windows open at a time. Memory usage sits around 50Mb to 100Mb per user. The server is also retrieving the incoming real-time data at a rate of about 50 records per second. CPU sits around 1%. Total memory usage is well under 50%. This is not an order entry system so probably not a comparable user environment.

>>I don't really know what you want to say with these stats. Are you saying the server is under heavy load and thus justifies the 10 user / max CPU usage? I don't know what a "hit" entails, what resources a "hit" uses. But 10 users = max CPU seems very onerous imo.

>>The server I described also acts as a web server serving remote requests for data directly feeding into end-user spreadsheets. It handles millions of data records in the charting databases, tens of thousands of records in multiple reporting databases, etc. It easily handles 20, 30 or more users. And I don't think it is a very high end server; just a single CPU, 16Gb ram. I could easily ramp that server up.
