Perfomance issue on different servers with almost same configuration


On some our dedicated servers doc file (254.8 KB) converts within ~50 seconds, but on other servers conversion takes just ~15 seconds (more than 3 times faster!).
All the servers we use have almost same configuration. We tried to run code on servers with/without Microsoft Office installed - no difference.

Issue is in Save method in code:
new Document("Test.docx").Save("Test.pdf", SaveFormat.Pdf);

Could you, give us suggestions how to find reason of the issue and solve it?



Thanks for your inquiry. It is quite difficult to answer such questions because CPU performance and memory usage all depend on complexity and size of the documents you are loading/generating. We have tested the scenario using latest version of Aspose.Words for .NET 17.9 and conversion process takes around 18 seconds. Please make sure that you are using the same document on all servers.

Moreover, please note that Aspose components are totally independent and are not affiliated with, nor authorized, sponsored, or otherwise approved by Microsoft Corporation.


Thanks. We also use Aspose.Words for .NET 17.9. And document is same for all servers. Could Aspose.Words use Internet, LAN to download/upload something? Or use some temporary files?

Best regards.


Thanks for your inquiry. You can use all Aspose APIs without internet. There is no issue to disable internet and use Aspose APIs. Aspose.Words writes temporary files to disk and automatically deletes them when saving is complete.
