PeopleSoft BenchmarksPeopleSoft Benchmarks Rule-of-Thumb: Application Server needs 6 Rule-of-Thumb: Application Server needs 6
times more processing power than a web times more processing power than a web server server
Estimate the concurrent usage patternsEstimate the concurrent usage patterns Categorize the users into light, medium Categorize the users into light, medium
and heavyand heavy
2525
AppServer Sizing
Estimate the number of Light, Medium & Power users
Estimated load by user type Light User TPC/C = 60 Medium User TPC/C = 100 Power User TPC/C= 30
For Example Calculation, Assume 500 light users 100 medium users 10 power users
2626
App Server Sizing
Calculating the TPC figures For 500 Light Users, 60 X 500 = 30,000 For 100 Med Users, 100 X 100 = 10,000 For 10 Power Users, 300 X 10 = 3,000
Thus Total Appserv TPC units = 43,000 You have to find a server that would deliver at
least this many TPC units Add any additional work load
Memory???? PS recommends 512MB per 25 users Add 1.5MB per each additional user
2727
Appserver Sizing: Remember!
Highly CPU bound Large memory foot print in psappsrv Memory growth may result in
fragmentation of main memory Watch for the recycle count to recycle
the appserv at periodic intervals. “Caching is good; Queuing is bad”
