I am not aware of our changes, but Chrome has changed the things recently quite a lot. It should be easy to try things with the latest to see the difference.

I was just using config defaults..

I can't delete it because there are formulas in the rows.

How do you fill in the values? Using xlsxInsert, xlsxAdd, and other transformation helpers?
Maybe you can use them to create the formulas dynamically as well instead of prefilling empty worksheet?

This runs for 2s on the latest jsreport 4.7.0. Are you able to update?

On 3.10.0 it runs for 57s for me. However, you have there many rows in the template that don't need to be there I guess. If you remove the rows from 5 to end, it runs for 2s.

This is documented here

I've tried the azure web app with all defaults and azure file share mount with defaults.
The import of Stock report showcase merge/full takes the same amount of time (10s) for both 4.7.0 and 4.3.1 jsreprot images.

Would you email me the data you have stored and the export that you are importing?

I see, so you use the reports extension to store the rendering outputs. You can find in the docs the cleaning configs here
https://jsreport.net/learn/reports#cleanup

See this mentioned here

You have two options.

Use unoconv extension which allows to convert docx to pdf
https://jsreport.net/learn/unoconv

Write two separate templates for docx and pdf. One using handlebars in docx template and second using html and chrome convert.

Do you mean the profiles/logs? This can be limited with this config. Default 1000

{
   "profiler": { "maxProfilesHistory": 1000 }
}

If you have a single instance license, then you should attach the license only to one server. The dev servers should be marked with config

{   
    "license": {
        "development": true
    }   
}

You will receive warnings in the studio and logs if you have multiple active servers with the same license.

If the question is that if you can apply the license key on one server, then stop the server and apply to a different server, then yes you can do this.
