**What**
I have created a new method on the cart service which is `addLineItems`, allowing a user to add one or multiple items in an optimized way. Also updated the `generate` method from the line item service which now also accept a object data or a collection of data which. Various places have been optimized and cache support has been added to the price selection strategy.
The overall optimization allows to reach another 9000% improvement in the response time as a median (Creating a cart with 6 items):
| | Min (ms) | Median (ms) | Max (ms) | Median Improvement (%)
|---|:-:|---|---|---|
| Before optimisation | 1200 | 9999 | 12698 | N/A
| After optimisation | 63 | 252 | 500 | 39x
| After re optimisation | 56 | 82 | 399 | 121x
| After including addressed feedback | 65 | 202 | 495 | 49x

**WIP Missing integration tests**
**What**
Update the totals calculation on the refund line to include the notion of tax inclusive
**Test**
- Update and add new tests around the refund
Fixes CORE-482
* feat(medusa): Tax inclusive discounts calculations (#2137)
**What**
- Calculate line adjustments correctly taking into account the tax inclusivity
- fix totals getLineItemTotals by adjusting the sub total with the original tax amount instead of the tax amount when the unit price includes the taxes
**Tests**
- The tests create a cart with a percentage discount of 15%, the cart includes 2 items mixing the tax inclusive and validate the items on the result cart as well as the totals on each item. I ve based my calculation validation based on what we have done + some articles around discount apply on price without taxes to validate the output.,
