This question already has an answer here:

We moved into a different building a couple of years ago. Instead of rewiring everything I elected to use the existing wiring. I tested it all and only replaced the defective wires. Currently, here is what I am working with:

Networking Equipment

  • Two Gigabit Managed Switches connected via fiber
  • Cat 5 solid core cable ran through walls
  • Cat 5e rated Wall plates (guess)
  • Cat 5e rated Patch Panels (guess)
  • Cat 5e patch cables


  • Gigabit Ethernet, SSD Drive, Win 7, Quad Core, 8GB RAM


  • Dual Gigabit Ethernet (Currently only using one), Traditional HD, Windows Server 2003, Dual Xeon Processors, 4GB RAM

The servers are connected directly to the switch via cat 5e cables. The workstations have the cat 5 cable ran in the walls to them, which are terminated to the wall plates and patch panels.

I know that the performance you get will be based on the slowest piece of equipment you are using. What kind of performance should I expect out of the above scenario? What should I do to improve the performance?

I have some users that have faster access to the servers than others. The users with the worst performance are those furthest away form the servers (110' - 150'). Programs ran locally on the machine run really fast. However, apps that access server files run slower. I would like to speed this area up.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • How many users? How many servers? Which Xeon Processors are those, as potentially those servers look like one potential bottleneck. – Austin T French Jun 8 '13 at 14:11

Wire cannot negotiate. The cables used to connect two Ethernet devices must support the highest speed both devices support. Otherwise, you must manually configure at least one end to operate no faster than the cable supports. If you don't, pain will result.
