Some facilities implementing Paceart Web Access may find that even when using multiple physical servers, there is still a noticeable performance bottleneck. The first bottleneck you will encounter when deploying the Multiple Server Configuration is with the Paceart Report Queue Server. This server processes requests to generate Paceart reports as PDFs sequentially, meaning that if multiple requests come in at one time, they will be queued and processed one after the other. Since each report can take on average 0.5 to 1.5 seconds to process, facilities that generate many Paceart report requests may experience delays in the delivery of Paceart reports. For example, if 10 users simultaneously request a single report, the last request may not be delivered for 15 seconds. This can be handled by implementing the Multiple Server Configuration with Multiple Report Queue Servers.

The Custom.dat file contains configuration settings that can be modified to suit your Paceart Web environment.
This file is installed when you install Paceart Web in the root directory of Paceart Web. By default, this location is C:\Program Files\Paceart Web\Custom.dat.
The configuration settings can be modified by editing the file in a text editor, like Microsoft Notepad.
