I have tried everything you have listed, and other things people on other sites have said to try and still takes 20 seconds for a PO, INV & packing slips to send and when I add shipping labels to the email it takes about 10 seconds longer. one our other system with less hard drive, memory etc. it sends anything very quickly. This system did until last week when we upgraded to 2TB and 32GB and the issue started. Help because this 20-30 seconds seems like I could walk down the street and back.
