Network Card Bottleneck?

post #1 of 17
Thread Starter 
Hi Guys,

My brother just got the 1000 megabit service from Hong Kong Broadband. When he ran the speed test, his speed was batting at around 130 mbps for upload and download. I know its already overkill but the ads said 1000 mbps

Anyways, according to the kung fu master tech installer, there might be a network bottleneck being caused by the NIC. Im kinda familiar with networking but i just wanted to make sure. Is there really a bottleneck? We checked his mobo and it was gigabit capable. He just purchased a gigabit router for this so were kind of hesitant to purchase a seperate network card only to find out that there is no difference. Also, are there any means possible to check if the nic is unable to keep up with the download speeds?

Try going to this website and running another speed test.

http://ndt.anl.gov/

It is the Argonne National Laboratory's NDT server. It may help you pinpoint the trouble.

Just want to check. Did you mean go to a site like speedtest.net and run a test? Or did you download a file? If you download a file You should be getting 100 MBps at 1000 megabits.

Incorrect. He should be getting 1000/8 (125) MB/s not 1000/10 (100) MB/s. There are 8 bits in a byte. Not 10. (not taking into account bits for encoding) That being said, I noticed you said your getting about 120-130 mb/s. Did you mean mb/s or MB/S? Because if it's the later wow....

Well 1000 mb/s ~= 125 MB/s, so yes that sounds about right.

You aren't going to get 130 MB/sec on a gigabit link.
Speedtest.net uses bits by default in it's measurement.

My connection speed is reported in megabits but it's tiny compared to yours. I get 15 megabits/sec download. Just notice if the B in mb is large or small. If it's small (mbps) then it is megabits/sec, if it's large (mBps or MBps) then it is megabytes/sec. That's the general rule. Sometimes though some programmers don't know about the rule and just use whatever standard they feel like.

I think ~130 MB/s is about right though.
