Adding A New Attenuation; Visualrf Resource Utilization - Dell PowerConnect W-AirWave 7.6 User Manual

NOTE: All of these values are global variables that cannot be overridden for individual floor plans. VisualRF uses these values to
calculate path loss and client locations. Walls within VisualRF are interpreted as pure dB loss without adjusting for wall thickness.

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.
