Item entry autocomplete very slow in Sage 100 2016 Premium

Hi,

We are moving to Sage 100 2016 Premium (SQL) and are having an issue with item entry autocomplete being glacially slow. We do not have this problem with our Sage 100 2014 Standard installation on the same server.  Vendor and customer autocomplete work well in both. I see that others have had this issue, but I haven't been able to find any solutions and I'm stumped. Any ideas would be greatly appreciated.
