Slowness/Timeouts when connecting to MS SQL Databases over ZPA?

Since migrating to ZPA we have been getting reports of slowness and timeouts when users are attempting to authenticate to MSSQL databases. If they go back to our traditional VPN solution there are no issues. We are not getting these reports for any other applications, only the databases. Anyone else seen this or have any ideas? We have had a case open with support for a while but they have not identified any issues.
