Thats funny - well I hope out-of-box Solaris is still better than other out-box operating systems. To answer your questions
0: Workload is divided into a) Basic OLTP SQL statements against PostgreSQL b) Operational and monthly reports against PostgreSQL c) Java ORM mapping d) Business logic e) Rhino scripting f) JBoss drools rules g) RMI TCP communication This is all backend server processing - no clients here 1: For a physician offices typically 4-20. Later though as I add more hospital information system processing there could be 1000's but I would scale horizontally keeping the number of users per server constrained. 2: Completing the service calls as fast as possible. 3: Java object creation, and read/writes from/to the filesystem (and whatever else makes PostgreSQL tick). > > Hard to say... > > Its always difficult to start a project expecting > gains just you are > running Solaris :-) and ruin it with the first > Out-Of-Box Performance > numbers because it wasn't configured right. > > A more detail about what the application does based > on the load it > drives can help answering your expectations better. > > Here is what I think will help your cause better > > 0.
