The sizing requirements can differ based on the type of profile deployment and size of the organization. To increase performance, you can optimize the Data Integration Service and Profiling Service Module and set up the required hardware. You can change the Data Integration Service and Profiling Service Module properties to match the profile deployment environment in your organization and optimally run the profile jobs.

You might need to consider the sizing requirements because of different reasons such as:

You can complete the following tasks as part of the profile sizing process:

Analyze the sizing requirements. You might need to consider the sizing requirements because of different reasons. For example, performance problems, such as profile jobs that do not meet expectations, slow response time to profile runs, and resource capacity planning for future growth can lead to sizing assessment.
Analyze the performance factors, such as the number of users, volume of source data, and profile types.
Analyze the Data Integration Service properties and properties specific to Profiling Service Module in the Administrator tool.
Use the profile sizing guidelines to calculate the required hardware resources and Informatica Administrator properties.
Make the hardware changes as required.
Make the Data Integration Service and Profiling Service Module property changes as required.
Monitor the changes to verify the required performance improvements. If you do not see the expected performance improvements, repeat the process from step 1.
