Hello!I've just finished to migrate all my production DB to a new SQL 2014 Box, built on an Hyper-v Guest.All is working well but we have found some issues related to the networkThe ERP Application make some queries to the DB to display a few reports, but since we are on the new server, some of them are really slow.I can compare the elapsed times directly to the old server and the differences are huge.Looking with some DMV I get that the wait that arise on the new server is ASYNC_NETWORK_IO. I know that usually this wait is due to the client, but the same client, if it points to different servers, havetotally different timings.The single query on the server is processed really fast (even on the old server) and the returned rows are the same. I've looked at the network configuration of the guest OS and the Host OS and nothing appears to be or under pressure.Does anybody have a clue to explain me this heppening?Thank you!
