Site too slow during import, Can we configure another server just for Import?

Site too slow during import, Can we configure another server just for Import? and have it map imports to Main Site

ie:
Main Site: Domain.com (For Public View)
Import Site: import.domain.com (For Import)

Theoretically, it's possible but it's not clear how two servers will work together

also, we can try to divide operations by different threads via nginx

you need to create a ticket for further discussions
