Magento indexes most of the data in order to access it faster. When any changes are made to the store such as updating some of the products, re-indexing the data need to be performed so that the changes can show up on the front-end.
In Linnworks this option is enabled by default.
Disabling this option may decrease listing creation time, as no re-index will take place on Magento after listings are created, and listings will be submitted to Magento faster. However, once the listings are processed, you will need to re-index your Magento - it can be done manually from the Magento back-end.
In order to re-index the products catalog data:
- Go to Magento Admin Back-end > System > Index Management;
- Select all elements;
- Choose the Reindex Data action;
- Click the Submit button.
