Performance issue with Aspose.PDF

Can you help?

We are now using Aspose.PDF 18.xx and Aspose.PDF 11.xx on our 2 production application servers. Both servers run on the same type of hardware and configurations. We are seeing following performance differences:

The 11.xx server runs tasks about 40% faster on average
The 11.xx server still infrequently hangs on multiple page/ multi-threaded tasks
The 18.xx server never hangs on multiple page / multi-threaded tasks
The 18.xx server runs tasks faster than the 11.xx server for small tasks (single threaded)
The 18.xx server task times telescope out when there are a high number of  multi-threaded tasks running

A task is taking a Word document with bookmarks, creating a PDF with populated bookmarks and creating a bitmap file for each page in the Word document. If the Word document has more than 2 pages, all the page image requests are done on separate threads.

Does this behaviour make sense to you? Would the changes made from Aspose.PDF 11.xx to 18.xx explain this behaviour?
