Web viewer extremely slow

[acataluffi]

Hello everyone,

I was developing some dashboards with a fairly large amount of data, but using simple queries (without using joins or unions).
From the designer, using the preview menu the dashboard runs extremely fast, but for requirements I need to show them via the web viewer.

From the web viewer, the same dashboards that used to take 2-3 seconds take a minimum of 40-50 seconds and this renders the use of the instrument useless. How can I solve?

I work in .NET Core 6 environment, BI Designer 2023.1.2 and last release of Nuget Package for web viewer

Hello,

Could you send us a sample report with test data that reproduces the issue for analysis?

Thank you.

I think that if i send my example with test data from json, performance can change.
Can i share with you a video? Or if u prefer i share my SQL Server Backup and mrt on e-mail.

Hello,

Ok, but on the video, we can see the problem, but we can't tell why it happens.

Thank you.
