One of the differences between raster and vector formats is that raster formats have specific DPI (dots per inch) and bit depths. Vector formats aren’t inherently black and white or color, and while they typically have sizing in inches, there is nothing that says what DPI or bit depth to use when rendered as a raster image.

When the content server pulls out a page from a vector format document, it must render that page to a certain DPI and bit depth, as well as save that image as some format to be passed to the client for display. (Sending an SVG version of the document for display retain the vector format and DPI is not necessary.) The particular settings are determined on a per format basis by three servlet parameters.

To improve the performance, you can save your files as black and white or grayscale. For example, if you are converting a PDF document, you can save the document in the TIFF_G4_FAX file format. This will make the file size smaller and improve performance.

Please note that there is always a trade off between performance and quality. To improve performance, the quality of the image may be less. This is true whenever working with any imaging software. Please note that depending on the operating system and configuration, certain unusual or corrupt documents or files can cause the software to crash. Potentially, in some unusual circumstances, files may not be rendered identically to the creator application and may not format correctly or miss information.
