How long does a discount rule apply to products and variants?

Please keep in mind that discount rule activation time depends on quantity of products. Also only one discount rule can be in process at one time - the rest will be in pending status.

The velocity of discount rule activation (or deactivation) is about 2 products per second, i.e. it takes 5 seconds to apply a discount to 10 products.

In addition, each discount rule may be waiting for the process to start up to 1 minute (pending status).

Discount rule activation or deactivation progress can be tracked near the status badge.
