We're observing slow submit order process for few customers who've 1000s of orders in their account. Order submit process take Approximately 2 to 3 Minutes to place order. We're placing order from admin.
Order submit is working fine for other customers, there are only issues with customers who've 1000s of order in their account.
We're using Magento EE version, Archive Sales Order functionality is enabled in system.
Current Magento version is 22.214.171.124
Any Idea what is wrong?
