Aspose.Pdf.Kit for.Net to Aspose.Pdf for.NET : decrease performance?

Aspose.PDF Product Family

Hello,

We just change component from “Aspose.Pdf.Kit for.Net" to “Aspose.Pdf for.NET”.

In our code, we have done well change the namespace “Aspose.Pdf.Kit” in “Aspose.Pdf.Facades” as you recommend.

Our entire web project compiles and runs.

However in performance, creation’s time is longer than before on a server with same setting.

On avergae for “Aspose.Pdf.Kit for. Net" : 5 seconds

On avergae for “Aspose.Pdf for. NET " : 25 seconds

Our web project is to load a PDF containing a single page.

Then write user’s data in specific areas of this page.

So then prompt user to download the PDF with data.

Is there a reason for this decrease in performance or a change (code, settings, …) we need to do to enhance creating a PDF?

Thank you in advance.

Hello Clément,

Thanks for using our products.

I am not entirely certain about the reason why the performance has been decreased in new version. Ideally it should have better or at least the same performance as offered by Aspose.Pdf.Kit for .NET. Can you please share some code snippet / sample project so that we can test the scenario at our end. We are really sorry for this inconvenience.

Hello, we are facing the same problem.


- there was a considerable reduction in performance when i use aspose.pdf 6.0.0 whenever I try to fill some value using Form.FillField.
- the background of textfields remain white, instead of been transparent
- wasn’t possible to change the encoding of the texts, unable to visualize the characters ç, ~, ´,`


Here a simple example and the pdf attached.
Form form = new Form(Server.MapPath(@“PdfToFill.pdf”), Server.MapPath(@“output.pdf”));
foreach (String str in form.FieldNames)
{
form.FillField(str, “ç ~ á”);
}

form.FlattenAllFields();
form.Save();

Here is an example of our web project that writes data in specific areas of the PDF file and saves it.

Thank you for your expertise and your help

Hi,

We do face the same problem with the new Aspose.pdf where the performance for the same code is very good in Aspose.pdf.kit.

Did you end up with any solution for this. Can you please share us the same.

Hello Caio,

Thanks for sharing the source PDF document.

I have managed to test the scenario and have observed that performance has been affected in Aspose.Pdf for .NET 6.0.0 when filling form fields. For the sake of correction, it has been logged in our issue tracking system as PDFNEWNET-29504. Our development team is looking into the details of this problem and we will keep you posted on the status of correction. Please be patient and spare us little time. We apologize for your inconvenience.

We are sorry for your inconvenience.

We read this "Issues: 29456 (Resolved); 29504 (Resolved)" in this request's top.

However, we do not have any update available to fix this performance issue.

We always have major problems of performance using the latest release of your product available.

Thank you for keeping me informed of your progress.

With the same example as we have posted at 07-27-2011, 11:36 AM and the latest release (6.1.0.0), We observe the following performance :

On avergae for "Aspose.Pdf.Kit for. Net" : 5 seconds
On avergae for "Aspose.Pdf for. NET 6.1.0.0" : 15 seconds instead of 25 seconds with previous release (6.0.0.0)

Yes, overall performance is improved with latest release (6.1.0.0) but they are still not equal to those of "Aspose.Pdf.Kit for. Net".

What is boring for our use of your product "Aspose.Pdf for. NET 6.1.0.0" to generate PDF files.

We did not meet the decrease in performance with the version "Aspose.Pdf.Kit for. Net" that is not followed.

Thank you for this performance gain.

However the performance of these two products are not the same when Aspose.Pdf.Kit for .NET has been merged into Aspose.Pdf for .NET

Hello Clément,

Thanks for contacting support.

I have again re-opened the issue regarding performance decrease when using Aspose.Pdf for.NET to fill the form fields. I have again intimated the development team to further investigate this particular scenario and look into the details of this problem. Soon you will be updated with the status of correction. We apologize for your inconvenience.

Hello Clément,

We have further investigated the issue and have found that this issues is related to PdfFileMend. We have separately logged it as PDFNEWNET-29975 in our issue tracking system. Once we have some definite news regarding its resolution, we would be more than happy to update you with the status of correction. We apologize for your inconvenience.

Hello;

I’m wondering if there has been any progress on this? We have had to revert to Aspose.Pdf.Kit 5.9.0.0 while waiting for this solution and are experiencing an issue with that DLL (which I will check for on your site to see if it’s already logged, and if not will log separately).
Many Thanks,
Elizabeth Plumley

Hello Elizabeth,

Thanks for your acknowledgement. Our development team is working hard to improve the performance of Aspose.Pdf for .NET but I am afraid the performance is not as optimized as legacy Aspose.Pdf.Kit for .NET. As soon as we have made some definite progress regarding its performance improvement, we would be more than happy to update you with the status of correciton. Please be patient and spare us little time. We are really sorry for the delay and inconvenience.

We encounter still the same problem despite various updates.

What is the resolution of this bug.

This is urgent for our start-up of our services.

Do you have a way or another method to generate a PDF file as in the example that we sent you there is over a month in less than 25 seconds.

Pending a solution,
Thank you for your help and advice.

In every new release version of Aspose.Pdf for .NET, we are trying our level best to provide more stable and better release as compare to its predecessors, however its been observed that during the migration of Aspose.Pdf.Kit for .NET code to new Merged API, there have been some performance related issues. For particular issue that you have been facing, can you please share some details and if possible, please share the code snippet/sample project so that we can test the scenario at our end. We apologize for your inconvenience.
