We use Aspose.PDF to produce a large document produced by concatenating a whole bunch of PDFs together into one large PDFs.
The original PDFs would consist mainly of scanned images, so people use their scanners to scan documents received in the mail to PDF documents
We also add footers to each page by inserting a little bit of text
One of our clients is complaining that they submit this functionality and it won’t finish for hours
The strange thing is… when I take the exact same set of PDF documents they are using, and I put it through the process here on my developer machine, it finishes in minutes. 2 to 3 minutes maybe, it’s done.
On the client PC we submitted the same process for the same set of documents and an hour and a half later it’s still ongoing.
Obviously their machine lacks the necessary resources to do this quickly, but can you advise as to what may be the most likely cause? Their processor seems to be ok - not stellar but ok. They appear to have sufficient memory.
So I’m wondering whether it’s possible that Aspose is leveraging processor speed from the Display card. It would make sense and it might explain why it’s so fast on my machine while it’s so slow on theirs, running as a VM in a data center.
