We are considering buying DocIO, and I'm now doing some demo of our needs.

I met a problem while writing and saving a large doc file which have a data table of more than 20,000 rows and 18 columns inside(total about 356 pages).
Now the time spent on writing the table is about 13 seconds while using mail merge, and about 21 seconds while using table object and add paragraph per cell. The total saving time is about 8 seconds.

Are there any other ways to get a more effective result?

Thanks for your attention,

Hi Benny,

Thank you for your interest Syncfusion products.

We had further investigated our DocIO table generation code, but we were not able to find any potential bottle-necks which could cause performance issue.
With our current version of Essential DocIO the performance has been improved.

Here is the comparison snapshot of performance when compared to our previous version.

Please find the sample from the below location, which we had used for this test.
