Processor speed and amount of memory have a very significant impact on response times. Workbench Processes discusses the common processes that demand significant memory and processor resources. Internal performance tests reveal that using PCs with older processors can result in less-than-optimal performance. So, it is important to have a client PC with a processor that has at least a 2 GHz dual-core CPU and at least 2 GB of RAM.

Workbench Processes discusses a number of common processes that demand significant processor resources on the server machine. For this reason, it is important that the server machine has enough spare processing capacity to handle the load.

All processes involving client-server interaction are affected by network speed; however, during data retrieval, the system transfers significant amounts of data from the server machine to the client over the network. System administrators should look for poor response times caused by network latency.

Progress administrators should ensure that there are a sufficient number of agents to service all concurrent QAD AppShell users; otherwise, the system can queue appserver requests from the client, resulting in poor response times.
