UPDATE: When looked into it, I realize that I have a lazy loading collection of entry codes, so each test had to spent time to resolve the entry code(s) from the content links. That actually costs quite a lot of time, and therefore causing the performance tests to return incorrect results. That was corrected and the results are now updated.
In previous post we talked about how loading orders in batch can actually improve your website performance, and we came to a conclusion that 1000-3000 orders per batch probably yields the best performance result.
But orders are not the only thing you would need to load on your website. A more common scenario is to load prices and inventories for product. So If you are displaying a product listing page, it’s quite common to load prices and inventories for all products in that page. How should it be loaded?

Recently I stumped upon this question:
which is very interesting to me. I can see this is a real scenario – and even quite common. When a price become obsolete, you want your contents to be reindexed so the next time you query, the search result will be returned correctly. But how?

This is an unusual post – as I usually don’t post sample code – that should be the job of the documentation. However, I jumped upon this question http://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2017/8/global-price-increase/, and found it to be an interesting case to demo.
It’s worth noting that as a customer, I’d like price drops, not the way around, so in this example, we will see how to cut prices of all products to 5%, instead of making them 5% more. Of course, it’s just simple mathematics, so you can change to the formula however you want.

It can be quite confusing when you first edit prices in Episerver Commerce. To your surprises, some of the prices you imported or edited might disappear, or change, without your consent! What happened?
To answer that question, it’s essential to know there are two pricing system in Commerce:
They have some different characteristics, and one of them is very important: the default implementation of
IPriceDetailService saves prices as-is, while the default implementation of
IPriceService does not: it optimizes prices before saving. Prices which are best for customers will be favored over the “less good” ones.
