now and then we have some performance problems in our application (deployed or localhost).
Config: IIS Version 10 on Windows Server 2019, SQL-DB on SQL Server 13.
In Chrome Developer Tools, I measured up to 20s of TTFB-time for one pageload. It doesn't matter if it is a complex page with e.g. many invokes for dropdown-datagrids or not.
Furthermore it can happen that when calling a dataset from a datagrid 10 times, no performance problems can be detected. On the 11th time there is again a high TTFB-time.
I am aware that this is hard to define, but maybe you know from experience about problems between IIS and SQL Server or there are tips for a better structuring of pageloads.
Thanks in advance,
