VisualRF Resource Utilization
When tuning the VisualRF server, use the default settings as recommended. If you do change any of these
settings, change one at a time and see how the system performs. Each time you restart VisualRF, you will notice a
delay before returning to normal processing. This delay can last anywhere from a minute to upwards of 30
minutes, depending on the size of the VisualRF database.
If you use the ‘top’ command to check on VisualRF resource utilization, ensure you use the ‘1’ and ‘H’ flags to
show cores and threads. Remember ‘top’ also takes 1-2 minutes to normalize and provide accurate data.
It is normal for VisualRF to consume 20% of each core with a combination of threads. It will utilize excess CPU cycles on
all cores when required.
Planning and Provisioning
VisualRF provides the capability to plan campuses, buildings, floors, and access points prior to the actual access
point deployment. The following procedure describes the workflow:

Creating a New Campus
Floors are associated with a building, and buildings are associated with a campus. In order to create a new floor,
you must first create a campus with at least one building.
