Necessary To Load Products In Cart / Checkout?

[sprankhub]

Still / again doing some profiling... I saw that in the cart and checkout, the extension fully loads all products from all quote items, which takes quite some time:

Do we really need to fully load the product in the cart / checkout?

By the way, mapByProduct is so expensive due to the loading of all categories:

@jissereitsma, do you have any thoughts on this? Thanks!

Good point. My thoughts? This should prevented. However, it requires some magic to do so. With the products, I already created now a draft for this: Introducing a new class that collects all product SKUs first, then fetches data for all SKUs at once, and then reuses them. https://github.com/yireo/Yireo_GoogleTagManager2/commit/f89fc8b80526c18feac85a0fec4d475d0f8d15bb

Perhaps this can also be used for categories. I'm on a holiday soon, so can only pick this up in 2 weeks time.

Ran into this same thing while profiling for a client. The GTM data loading and rendering (products and categories) takes 30 seconds for us on a 300-item cart, ~90ms/product.

In our case we're not even sending any custom product attrs, so the loading is unnecessary, all product data is already on the cart item product.

Thanks @rhoerr for chiming in. The product load should be a lot less now already, but I'll still work on the same thing with categories. And indeed the "hydration" seems a bit much if it is not needed after all - I'll also check for that to see if that can be made more flexible.

The previous fix already brought the load down to a minimum, but with the new release 3.7.6 I also refactored the categories part, so far less queries are needed.

As of yet, I'm closing this issue, but let me know if this is still bugging.
