Hi AC -

We just went live with an updated store yesterday (ver 9.0.6.7222) and are using Braintree payment gateway in production mode. When paying via credit card and Apple Pay, the transactions take 17-19 seconds to complete. When testing this locally on my VM and local DB server using the Sandbox Braintree implementation, the time after hitting submit to see the order confirmation screen is ~5 seconds.

Have you seen this behavior before? We do not have debugging turned on in the settings area, and have tested multiple orders and devices, all of which behave this way. I tried rebooting the server to reduce the chance there was some temporary issues, but the problem persists. I did run inspector tools and watched the network traffic which shows the path /Checkout/_CreditCardPaymentForm/149?Length=8 is the process consuming that time, and shows 'waiting for server response' as the most time intensive process (I have screenshots but don't see a way to attach them here).

Thank you for your help; this amount of time will be confusing for end users and cause issues so I'm eager to get it resolved quickly.

Thanks,
Greg

Hi,

I did a test using sandbox details and got the response within 5 seconds. I am not able to test with the production environment.
I suspect the Braintree server is taking the time.

On the final checkout page, open the browser console before the FINAL CHECKOUT. Click the button and see when a nonce value appears in the console logs.
AC backend processing starts after we got the nonce value from the Braintree server.

Hello -

We sorted this out. It turns out that we had an inefficient use of custom fields data that caused a major slowdown when in production. All is good now - thanks for the help!
