Got a new gigabit switch

My network (all computers with onboard Giga NIC) was on the switch of a regular Router and yielded about 8MB/sec. local transfer.

I left every thing as is just plugged the computers and the Router to a rock bottom inexpensive Netgear Switch I mange to get about 20MB/sec. LAN transfer.

I left again every thing as is and replaced the D-Link with an Inexpensive Trendnet Giga switch. Now I am mastering 58MB/sec. LAN transfer (that is a real transfer of large files not he short bursts of ipref). :thumbsup:

I don not know whether the specific unit of the Netgear was Bad or that is the performance of all of them.

I basically stop buying Belkin, D-Link, and Netgear. Here and their they might release a good model but most of the time their Hardware quality is random.

Same for new retail.

This was $20 used, so I figured at worst it's $20 "thrown away". Figured it would be a safe bet, and asked the seller about it prior to buying it. Per the seller there were no issues with it.

Most sellers know "diddly" about Networking, and usually the same goes for guys that buy it from them, you are the exeption.

It might be that what ever the switch did seemed good for him.

In any case this cost almost the same and it works well, http://www.newegg.com/Product/...x?Item=N82E16833156250

That switch had a 5-year warranty. The original owner might be able to RMA it if he can find the receipt and confirm the purchase date.

I have the info from the owner (emailed a copy of the order actually), and will call dlink monday to see about an RMA.

Update: Called DLink to see about an RMA. Ultimately ended up talking to a level 3 tech support guy that was very helpful. After talking about it with him, he said it sounds environmental(i.e. my network specifically and how it's setup) which the symptoms point to (if we assume the previous owner didn't have any issues with it). So, he asked if I could test it using a different environment (which is fair enough), so I will be using it on a different network and run the same tests on the other network.

While it's not a new switch, I think it's fair for me to test it in another network based on the results I'm seeing before they RMA it.

I still think you've got something spewing out packets on a machine or some application/program causing this if you have totally eliminated physical layer/duplex. Have you tried loading up wireshark and getting a packet trace?

An issue that would only show up on the Gig switch, but the 10/100 is fine with everything else being the same and only changing the switch? I've eliminated cables, tried different ports on the switch, and checked duplex settings (all were auto-sense, but also forced full duplex with no significant change).
