We've got our main database that uses an ODBC connection back to our SQL server 2016. It is an access front end with a SQL backend. We're hopefully replacing it with a new SAAS database, but that won't be until later this year. The SQL server vm is a Windows 2016 datacenter VM with around 64gb of RAM and is running SQL Server 2016 Enterprise.
For most users at our main site, there are no problems. At our remote sites where the users connect via a site to site VPN, there are a lot of ODBC connection failures, especially during peak use times.
Are there any ways to optimize ODBC connections or improve on them somehow? Is there some traffic shaping that should happen on our firewall (a Sophos XG 135) or something?
