In my project there are two servers local and central. My central server is in Network1 and local server are in any network(like Network1,Network2 etc). I wrote a procedure to delete and insert data from local to central but it is taking 45 mins from network2 to network1. If local and central are in same network(network1) then it is taking 3 mins. We are using linked server to connect two servers. Please suggest me how to improve performance in cross network. How to check what is creating the problem?
Thanks in advance.
