 Two places to get information on process model memory usage are:

• Process monitoring tab. The process monitoring tab is a feature in the Appian Designer that allows you to monitor and manage the performance and status of process models and instances. You can use the process monitoring tab to view various metrics and statistics about your processes, such as memory usage, execution time, node count, error count, etc. You can also filter, sort, and export the data for further analysis. The process monitoring tab can help you identify which processes have the highest memory footprint and potential performance issues.
• Appian Health Check report. The Appian Health Check report is a tool that provides insights into application design patterns and performance risks in your environment. The report covers four areas of your environment: design, user experience, infrastructure, and configuration. The report also includes graphs highlighting historical trends, such as user activity, average response times, and resource utilization. The Appian Health Check report can help you identify which processes have the highest memory consumption and suggestions for mitigating them. References: Process Monitoring Tab, Understanding the Health Check Report

A connected system is an Appian object that is designed to allow you to share base URL and authentication details across multiple integrations4. A connected system represents an external system that is integrated with Appian. Connected systems allow you to easily connect to external integrations and data sources. They also allow you to deploy connection information across environments and use different connection information for each environment. You can choose from different types of connected systems, such as HTTP, SQL, or pre-built connected systems for common services like Google Drive or Salesforce5.

 Two things that can be done to increase the performance of a poorly-performing process model that has a lot of nodes and is mainly used to do background updates are:

• Remove all activity chaining. Activity chaining is a feature that allows a process to move from one node to another without waiting for a commit point. This can improve the performance of some processes, but it can also cause memory issues and data inconsistency if used excessively or incorrectly. Removing activity chaining can reduce the memory consumption and ensure data integrity of the process model.
• Refactor some nodes into subprocesses when possible. Subprocesses are processes that are called from within another process model. Refactoring some nodes into subprocesses can simplify the main process model and improve its readability and maintainability. It can also reduce the memory usage and execution time of the main process model, as subprocesses are executed in parallel and have their own memory allocation. References: Activity Chaining, Subprocess Node, Process Model Best Practices
