Hey folks,



Just a bit curious about something I heard.



A company IT department Director told a VP that the reason some folks pc's were slower than others is that when the installation of the network cables was performed, some of the cables were "kinked". And therefore those people would naturally get slower response times... blah, blah, blah.



I'd like to find out if anybody out there has experienced this phenomenon.



Thank You,

Sounds fishy :-) replace the cables if faulty or low quality, when cost benefit to do so.



BTW, I am no expert, so my statements may need to be verified etc.



But I would tend to believe that there is a possibility that a kink may cause some signal degradation, this may be minor, i.e. when a data packet is sent; the sending PC requires an ACK acknowledgment packet back from the receiving PC to confirm that the data packet was received successfully. Packets contain various information about themselves; i.e. packet size, CRC checksum, packet number, this helps the receiving PC to check for errors/corruptions (if packet is corrupt the receiving PC communicates with the sending PC to notify of this and to request that the packet is resent etc, which may cause delay) and to put/join the packets back in the correct order etc.



Guess - Maybe at the point of the proposed kink some signal may bounce back causing interference or signal to be unrecognisable? - Maybe the metal at the kinked area is tempered and its resistance is different and has some impact on the signal?



There are many other factors that can impact on a PCs network performance/response time.



Assumption: If PC(X) has good performance because it is connected to a network via a non-kinked cable, then take this cable and replace PC(Y)'s kinked cable with PC(X)'s and then retest/benchmark PC(Y)'s new response times etc. If PC(Y)'s performance remains bad then indicates some other cause.



Just some ideas; my 2c

If the wires were bent to the point where they were marginally broken, it might cause intermittent failures, but I can't see it just causing slowness. Network cables aren't like garden hoses that can have flow controlled. I say that electrons either travel, or they don't.

Chris, the ONLY thing that I am aware of related to ethernet cords and
performance is the length of the connection between PC and
router/switch/etc.

I agree with Rick.

My experience with PC network performance issues is that they are
usually caused by a misconfiguration issue between PC and network
switch.

You should take a look at the following items:
1. Check the network switch port for errors (FCS errors, in particular)
2. If errors are found, check the port and duplex settings of the switch
port. The most common setting is 100/FULL or Auto-Negotiate.
3. Set the PC port and duplex settings to match your switch port
settings. (If switch port is 100/FULL, set PC to 100/FULL)
4. Reset the switch port error log and monitor the switch port to see if
any errors recur

If you don't want to get your networking group involved, you can always
skip steps 1 & 2 and try various combinations of PC switch/port settings
until you notice an improvement in performance.

Let me know if this works for you.


Thanks,
Michael

I agree with Rick *if* the cable is cat5. But if it were good old "fat"
ethernet which is co-ax then yes, sharp bends are known to degrade signal and
introduce interference on this type of cable.

Chris:

If you have not been told this, the story is false. If the wires were kinked enough to slow data down, they would not work at all.

You know of anyone using the old 10Base5 (it is a 1/4" thick coax cable) anymore?
