Would changing the concurrency speed up a data flow in the Shopify integration app?

Q: When we run our Shopify Order to NetSuite Order Add flow, it takes 12-14 hours for 5000+ orders.  Would changing the concurrency help with this? 

A: Changing the concurrency for the Shopify connection is not recommended and it would not have any impact on retrieving orders from Shopify.

However, increasing the concurrency for the NetSuite connection is recommended and it will speed up data processing. If it is increased, you should consider the number of integrations to be done for the connection with the same account. For example, if the RESTLet concurrency is set on the highest level of "10" and there are 11 calls at the same time to the NetSuite account, considering calls from other integrations/connections, this will result in an error in integrator.io.
