I am not sure which chat makes the most sense, so if this isn't the one just tell me to kick rocks 🙂 We are looking through some issues with speed within our SCA site, specifically with submitting an order. Looking at the APM for suitecommerce I can see that our average time for an order is over a minute, below is a screenshot of an order that took over 96 seconds to save. I was seeing what scripts may be causing the delay but it looks like the user event scripts, workflows, and custom client url scripts take ~7 seconds. Is there a way to see where the other ~90 seconds is going?

is it slow in the Webstore UI, too?

I may misunderstanding due to a lack over knowledge on the netsuite side. This is from orders placed in the suite commerce advanced site we have. Saving orders inside the basic netsuite UI (is that the webstore?) is also painfully slow though a median of 45 seconds instead of over 60. The graphs from the APM for this show large amounts of time with nothing attributed to it. I assume these are going to be related and that those missing spots could be the cause of slowness in SCA, but I am not sure how to find what is going on there.

Have you tested enabling "asynchronous aftersubmit sales order processing" for webstore

This is a good callout, unforutnately that is turned on and has been on for even longer than I have been aware of that option.
