Slow performance of Aspose.Slides in Android environment (Android via Java)

I am trying to convert office files to pdf format.
For cells and words this is working quite good but for presentation I am experiencing really bad performance.

For example I have a file with 425 kb and following code:
val output = ByteArrayOutputStream()
val presentation = Presentation(“Test.pptx”)), SaveFormat.Pdf)

Loading the presentation takes around 2500 millis
Saving as pdf takes around 67500 millis

I often read about an initial warm up of the library which could take some time but this is really bad.

Is there anything I am missing?

I am using Aspose Total for Android via Java in version 19.9

I am running the code on a Pixel 2 XL with Android 10.
