Thin Client Scanning Performance Limitations


Question / Problem: 

Scanning into the Kofax Front Office Server (KFS) Thin Client is slow when using a Production-level scanner.

Answer / Solution: 

Kofax Front Office Server Thin Client Scanning is designed for ad hoc scanning using a Desktop-level (under 40ppm) or Workgroup-level (under 90ppm) TWAIN scanner.


Due to the performance limitations inherent in browser-based scanning, KFS Thin Client scanning cannot support the scan speeds that Production-level (over 90ppm) scanners are capable of achieving when scanning into Thick Client scanning applications.


Factors such as image size, color depth, image resolution, TLS encryption, available network bandwidth, and number of hops between the scan station and the KFS server may affect the scan speed and upload performance.


Tips for maximizing scan performance with KFS Thin Client Scanning:

  • When possible, scan in Black and White or Grayscale
  • When possible, avoid scanning at 300dpi or above
  • Use a local installation of Kofax VRS to perform image processing of scanned images as it is able to process images faster than the WebCapture Service's built-in image processing.
  • Connect the scan station to a Gigabit network using the LAN connection (not WiFi).
