If License Metering is occupied by constant instant balancing, scheduled license balancing and general response speed suffer. A high rate of instant license balancing can be caused by many clients being denied access to application licenses in a short time period.
This may be because you have enabled Force real-time license verification, Force license limits for this product, and have disabled Do not enforce license limits for this product until a trend has been calculated in the Software Metering Properties dialog box in the SMS Administrator console. Alternatively, you might have uninstalled a software metering server site system that contained licenses for a product.
