Ethernet switch problem
Hi Correspondents,
I've got an Acer desktop that I recently upgraded with a quad core Q6600. Great. I recently purchased an Acer E15, also quad core. OK. For a long time I have connected my PC farm using a five port Ethernet switch, D-Link model DES-1005E. Both machines sport Giga Ethernet I was having problems with the connection which never went Giga. Thinking the cable was the problem I went with a new Cat6 Ethernet cable. No difference. So as a way to diagnose the problem I removed the D-Link switch and connected the two Giga quad core machines direct with the Cat6 cable. Problem solved. But, there are all the other farm computers to connect. The D-Link switch was better than my previous solution, a hub in a router and it only cost $20 at the Source. QUESTION: Should I ditch the switch? Can I get a better switch on my small budget? Thanks in advance. X |

QUESTION: Should I ditch the switch? Can I get a better switch on my small budget? Thanks in advance. X According to this, the DES-1005E is 10/100BT. No GbE in it. http://www.staples.ca/en/D-Link-DES-...4_2-CA_1_20001 I bought my GbE switch for $40 years ago. I'm sure you'll find something. I initially had 10/100BT and upgraded to GbE. And naturally, just between machines in the room, as there's no way any ISP will give enough speed here to justify a better WAN side connection. I'd have to move to Kansas (Google fiber). Not all desktop GbE chips are equal. There are some RealTek PCI bus ones, that seem to generate too many interrupts, and by extrapolation, you'd need a 4GHz processor to get the chip to deliver full GbE. Not all hardware is cursed with this degree of CPU dependency. Most of the work is supposed to be done via DMA and buffer queues. Paul |

QUESTION: Should I ditch the switch? Can I get a better switch on my small budget? Thanks in advance. X I guess that the first question before "Can I get a better switch on my small budget?" should be "Do I _need_ a better switch?". Only you can answer that, of course, but do you routinely do things which actually require faster transfers? Would it save me time? Do my computers have the horsepower to actually use the gigabit transfer rate? (I find that most real-world systems are hard pressed to average much over half gigabit speed under the best of conditions). If you decide to make the leap, you can find a selection of small gigabit switches on Amazon for $20. |

Hence I will be looking for a 4 port Gigabit PCI adapter Boxing Day. Intel is a good name. I am going back to Gogo IPv6 tunnel adapter and there are nuisance performance issues. |
