Hi,

Current i am testing my code in Aspose.PDF 6.2 version which we recently bought. I am having few issue on the performance and file size, i didn't see this issue when working with Aspose.PDF.toolkit (not sure which version as it was trial and i have already removed it)

1. Its extremely slow. I am concatenating around 1000 pdf each on avg 6 pages to one huge pdf
2. The output file size are huge. Not sure why as it wasn't like this when tested with Aspose.PDF.Toolkit

Please let me know, if the new build will address this issues.

We are about to release a new version of Aspose.Pdf for .NET 6.3.0 with some improvements/enhancements. Please try using the new version and in case the problem still persists, please feel free to contact. We are really sorry for this inconvenience.

Hi Nayeer

Aspose.PDF 6.3 concatenate has differently increased the performance by 100fold. Thank you for such a great turnaround

But i think there is still a question about the file size not sure if this issue is still pending. but here is what i am looking at.

I am using Aspose Word 10.1.1 build and Aspose.pdf 6.3. I use Aspose Word module to save them as pdf and pdf module to save each pdf as one large pdf.

Aspose 10.1.1 and Aspose 6.3. compliled in .net 3.5
Machine: OS Windows XP, Sp3. 3.0 GHz, 2.5G Ram

Current file size mutiplies so if i have 

35kb word document, then aspose word will save that to say 80 kb pdf file then merge each of this pdf 500 times you will have one pdf file size of around 38mb. If i have 2000 files that i need to merge to one pdf then that file would be huge. Is this something you are aware of and is something that would be fixed in new/later build.

Let me know if there are any questions.

Any updates on this ?

Hi Ujjwal,

Thanks for sharing the details.

You may consider using a workaround where you are first merge all the source Word files into a single document and then convert it into PDF format. I am not entirely certain about the resultant, but may be it can help you to produce a resultant file with smaller size. For more information, please visit Joining and Appending Documents

In case you have any further query, please feel free to contact. We apologize for your inconvenience.

Hi Nayyer,

I have already tried that process, infact that is the process currently used in production to merge the large amount of word documents to one pdf, But it is very unstable and time consuming.

Current run time in Prod is around 15 min just to merge around 6000 pages. 6000 pages is nothing compared to what we want to achieve, we want to be able to merge 20000 pages and more.

And there are always random errors when only using Aspose.Word

1. when there are too many formats used in word document, it crashes.
2. letter count gets bigger than 8000 page (sometimes 6000) it uses too much memory so it ends up crashing.

This was the primary reason why we purchased the pdf product. So that we can process this faster and efficiently without having to worry about when the program will crash if the file size grows. and I'm very disappointed with the Aspose.PDF as we tested with aspose.pdf.kit module which ended up being discontinued so we went with aspose.pdf module thinking it would be the same, that was our mistake, we should have tested it before we made this purchase. What do i say to customers or management ? This is very frustrating.

Does Aspose team understand the criticality of this issue and how dissapointing this is? Can i use Aspose.pdf.kit instead of aspose.pdf, i dont know how long do i have to wait for this issue to be fixed.

Thanks.

Hi Ujjwal,

Thanks for sharing the details. I have observed that the performance while generating the resultant file is decreased and the size of resultant file is increased. For the sake of correction, I have logged this problem as PDFNEWNET-31533 in our issue tracking system. We will further look into the details of this problem and will keep you updated on the status of correction. We apologize for this inconvenience.
