The speed of inking is significantly affected by the performance of your device and the other processes that are running while you are writing. If you are experiencing problems with slow inking, try the following:

- Disable Pressure Sensitive Ink (App Options > Annotation > Pressure Sensitive)
- Reduce the size of your PDF (large PDFs such as textbooks can put a heavy load on the application) by splitting it up into smaller parts for annotating.
