MuPDF is a small and fast PDF viewer that can quickly open large PDF files, even on slow computers.

Larger PDFs (such as those 20Mb+ ones available at Archive.org/details/texts) run miserably slowly in Evince, or about any other PDF reader/viewer I've tried in Ubuntu, to the point of being unusable. With MuPDF, they can be read (even on my aging hardware) quite rapidly.
Since the application focuses on speed and small code size, it doesn't come with interactive features like for filling for instance. Also, the user interface only displays the PDF; to navigate through the PDF file (next page, rotate, zoom, search for text, go to a page and so on), you must use keyboard shortcuts as explained HERE.
MuPDF also comes with a few tools (in the "mupdf-tools" package) that allow you to convert a PDF file to a series of images (pdfdraw), repair, decrypt, and decompress PDF files (pdfclean) as well as some debugging tools that lets you extract fonts from PDF files, display information about internal objects, etc. (pdfshow, pdfextract and pdfinfo).
Install MuPDF in Ubuntu
MuPDF is available in the official Ubuntu repositories so to install it, use the following command:
sudo apt-get install mupdf
To install a newer version for Ubuntu 12.04 and 12.10 (the one in the repositories is very old), you can use the official MuPDF PPA:
sudo add-apt-repository ppa:mupdf/stable sudo apt-get update sudo apt-get install mupdf
MuPDF isn't available just for Linux, the application is also available for Windows, Android and iOS:
