>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.
