Regarding performance issues in BIRT version 4.20

Regarding BIRT version 4.20, what is the maximum data volume it can support rendering? For example, if there are 900,000 records that need to be rendered on a browser page, approximately how long would that take? thanks.

900k records on a browser page simply does not make sense.
Regardless of how fast or slow that would be.
Anyway, the answer is: "it depends" and you'll have to test this yourself.

The actual situation is that we have already tested it and it cannot be rendered, which is why we are consulting with you. What is the maximum data volume that the BIRT engine can support for rendering?
thanks.

AFAIK there is no fixed limit. Only resources (CPU, IO, memory and time) limit the practical usability.

Reconsider what you actually want.
Displaying a million rows does not make sense. Never.

Instead, let the users filter what they want to see beforehand.
That why there are databases. And BIRT works very well with them.

Even if you want to just create a file, a million rows will be problematic.
Probably you won't be able to open it with ,say, MS Excel later.
You'd have to use pure text formats like CSV then.
For this kind of workflow, use a different tool instead of BIRT, because BIRT is for creating human-readable "formatted" output formats, thus there is a lot of overhead for all those formatting properties.

I confirm the explanation of hvbtup.
It is completely dependend of your test case, your content your rows and what you try to create.

In the past I had situations that the result was genereated but the HTML-preview couldn't be displayed due to the browser limitations.

If you provide more details to your test case and your target or you can provide your test-report with your demo data then I can try to execute the report on my side.
