Why does my form take so long to process?

Note: The average form on an Intel Core i5 CPU takes around 2 seconds to process when scanned at 300 DPI in black and white. The generally acceptable range is anything up to 6 seconds per form.

Slow form processing can be caused by a number of issues:

  1. You aren't scanning in black and white mode - you are either scanning in Color or Grayscale. Color and grayscale images can be 20 times the size of a black and white image. Because FormReturn has to load this data and convert it into black and white, much more time is taken to process the image. It is advisable wherever possible to always scan in black and white (NOT GRAYSCALE AND NOT COLOR).

  2. You are scanning the form at a resolution higher than 300 DPI. Lower the resolution to a maximum of 300 DPI and a minimum of 200 (though 300 DPI provides the best detection results).

  3. You have a slow computer - this can be either caused by an old computer (greater than 4 years old), virus scanners scanning files in the background (slows everything down), other programs consuming too many resources or you don't have enough RAM (we recommend 2-4GB depending on your operating system).

  4. You don't have enough RAM - FormReturn uses a lot of RAM when publishing and processing forms. It is advisable to have at least 2GB of RAM. If you don't have enough RAM, your system will start using your secondary storage for memory (which is much slower).

  5. You have a lot of other programs open (consuming a lot of RAM).

  6. You're running FormReturn networked (server and client are remote from each other) and the network doesn't have a high throughput. You should look at upgrading your infrastructure to 10/1000 Ethernet.
