Troubleshooting a Slow LAN4
This paper describes possible solutions for slow LAN performance. This paper is written in partial fulfillment of the requirements of TCM 537 '' Networks and Data Communications I, the 11th class in the MS CIS program at the University of Phoenix.
In a world where everything seems to be connected to a network, slow performance is one of the most irritating and solvable problems. For a person who is “learning the robes” in troubleshooting workstation and LAN performance, the table of troubleshooting slow LAN issues and how to solve them, may come in handy.
This set of troubleshooting scenarios assumes that this is a mostly Microsoft platform network, with Ethernet network interface cards.
Troubleshooting a Slow LAN
|Reasons: |Solutions: | |1. RAM in workstations. |• Increase RAM to prevent paging issues with virtual | | |memory. | | |• Increase virtual memory file to be at least 1.5 times | | |the amount of RAM. | |2. CPU in workstations. |• Get Pentium IV CPUs with L2 cache (512 KB) on the | | |processors to permit lightning fast data reuse. | | |• Ensure that the bus speed on the motherboard is at | | |least 133 MHz or better. | |3. Increase in number of nodes. |• Analyze network to discover traffic patterns, top | | |talkers, and top listeners. | | |• Segment the network into smaller segments to decrease | | |the possibilities of collisions. | | |• Also, ensure that the NICs are 10/100 BaseT, and that | | |the cabling is a minimum of CAT-5 UTP. | | |• Recommend switches over hubs, because of greater | | |throughput and better efficiency over standard hubs. | |Reasons: |Solutions: | |4. Increase in traffic and loading. |• Analyze network to discover traffic patterns, top | | |talkers, and top listeners. | | |• Segment the network into smaller segments to decrease | |...
