If your payroll posting is taking a significant amount of time to post due to a large transaction volume, you can set up Microsoft Dynamic GP's Distributed Process Server to send the payroll posting process to another computer on your network. This reduces the workload of client computers and improves posting performance. The client computer used for data entry will be immediately available to perform other tasks, so you don’t have to wait to continue working while the task is completed, or work more slowly while the task is completed in the background.
To set this up, see the Microsoft Dynamics GP System Administrator documentation, specifically Part 3: Distributed Process Server. https://docs.microsoft.com/en-us/dynamics-gp/installation/systemadminguide#part-3-distributed-process-server
When setting this up for TimeTrack payroll posting, in the DPS Setup window, select Third Party and then mark the Remote check box to the left of Payroll: Signature Post.
