Rules of thumb
Do signiﬁcant objects have more than a few million records ?
Do you anticipate a thousand concurrent users or more ?

High Level Steps - Test in your Developer Org
1 Single User Test in a Developer Org Pre-Requisite
Why is step 1 a pre-requisite ?
●  Is your application designed well ?
●  Does it follow Salesforce coding best practices ?
●  Triggers Bulkiﬁed, Selective Queries, View State minimized ?
Max 10 concurrent users in a Developer Org

Test with 10 Concurrent Users
Critical Steps
Know the rules
High Level Steps - Test in a Large Data Volume (LDV) Org
13

•  Open up a case 2 weeks before start of testing
•  Mimic normal realistic “thinking time”
•  Concurrent user test loads should be realistic
•  Salesforce does not support stress testing
•  Test only against sandbox instances
TESTING LOAD EXAMPLE:
5K users * 5 processes/ hour = 25 K processes /hour
1 business process = 3 transactions
25K processes/hour = 75K transactions/hour
Equates to 20 transactions per second (TPS)
Average load< 40 TPS
Moderately heavy load 40-100 TPS
Extremely Heavy load> 100 TPS
Salesforce will not provide back-end logs or results
Step 4 - Rules & Requirements
14

 Number of Atomic database actions* performed by a certain entity per second
Page DB Save DB SaveTrigger WF update DB Save
JS Query
JS
Page
DML
Single Transaction
Transaction 1
Transaction 2
What is a Transaction (Force.com context) ?
 * Atomic action = guaranteed isolation from concurrent processes
