What platform is your app built on?
Making a guess here, you need to identify and isolate your potential bottlenecks, here are my suggestions in order of culpability:
1. Database:- Watch that database like a hawk! I would bet my money on it being the culprit. There's this app called Spotlight on SQL Server<http://www.quest.com/spotlight-on-sql-server-enterprise/>, see if you can get your hands on one.
ok
2. Application Platform:- Is it .Net, Java etc, each comes with its own "environment" which could be the culprit
VB. Form based not web based app
3. Operating System
WIN2k3
4. Network
No sure I understand this bit of the qstn

Skunkers,
Here's the scenario:
There is a core application that is build on a 2 tier client/Server architecture.
Total number of users at any one time over a WAN is approx 100.
The app runs on a MS SQL 2005 DB that resides on a Primary server whose specs are as follows:
1. RAM: 40 GB 2. CPUs - 8 Proliant QUAD Core E7320 2x2M cache processors 3. Network Interface: Gigabit ethernet card 4. RAID 5 config for the main DB drives - where the main DB files reside. 5. RAID 1 + 0 config for the log files on a seperate disk 6. WAN traffic is on 256k/256k links from satellite locations
The problem:
1. As users are being added into the WAN, performance has been deteriorating. 2. On report generation, everything seems to crawl to a halt.
*What are the likely contributors to performance degradation*?
