Xerox FreeFlow® Print Server IPDS Network Connectivity Appendix Performance Notes The Xerox FreeFlow Print Server IPDS printers are very high speed devices compared to many other network devices. It is possible that in some configurations, you may find printers running at less than the rated print speed. In a typical installation, tuning for optimal printer performance can be complex, since there may be many different network components between the host system and the printer. This section provides some pointers on where to look in the event that you experience print speed degradation. Like any tuning activity, this is a process. You must first find the "Current Bottleneck" and alleviate it. Then you repeat the process until the printer throughput is at the expected rate. Ensure that both the PSF and TCP/IP address spaces are receiving a high level of service. Should you notice any printer performance problems, such as throughput speed degradation, check the areas listed in the following table: Table A-5. Components to Check for Printer Performance Problems TCP/IP If the printer is on a network that also has a large number of other devices attached to it, the high levels of traffic can cause printer speed degradation. Consider moving the printer to a network that has less activity. Host system to network attachment If the speed of the link connecting the network with the printer attached to the host system is slow, this could be a bottleneck. Review your network configuration diagrams for any potential bottlenecks. IPDS User Guide A- 7
