How can I speed up discount calculations at checkout?

As an e-commerce business owner, I'm struggling with slow checkout processes during discount applications. Our current system seems to lag when calculating complex discount rules, leading to customer frustration and potential cart abandonment. I need strategies to optimize our discount calculation speed without compromising the complexity of our promotional rules. What technical approaches can help streamline this critical conversion moment and ensure a smooth, fast checkout experience?

TL;DR - Quick Answer

Growth Suite discount codes are applied at Shopify checkout natively and do not add processing delay. The code validation happens server-side through Shopify's checkout API, which is optimized for speed. If checkout is slow, the bottleneck is typically Shopify plan limitations or third-party checkout apps, not the discount code itself.
