Determining the Working Set Size of a Project
The following example is a continuation of the previous example, and it uses the same project.

By inhibiting cap enforcement, either by raising the cap of a project or by changing the minimum cap enforcement memory pressure value (see rcapadm(1MSRM)), the resident set can become the working set. The rss column might stabilize to show the project working set size, as shown in this example. This is the minimum cap value that will allow the project's processes to operate without perpetually incurring page faults.
