I have ASP .NET MVC 6.0 business web application. Adding reference to Aspose.Pdf library rapidly slows down each request/response time. After adding reference with no additional source code change, each new request to controller and display simple web page takes about 12 seconds more. It is tested with / without reference. I tried to monitor web traffic with Fiddler and no additional requests are made.
Kindly let us which Aspose.Pdf for .NET API version you are using? Please prepare a small MVC 6.0 project application which reproduces the problem of slow response time in your environment, and then send us a Zip of this project. We will investigate and share our findings with you.
