I've gotten confused on this problem way too many times.. I'd like to |
2 |
get some definitive starting points. |

When you see net adapters online they are always rated like |
5 |
|
6 |
10/100 or 10/100/1000. So how does one turn that notation into |
7 |
megabytes? |
8 |
|
9 |
I think those numbers stand for bits, right? |
10 |
|
11 |
But still, when I'm trying to measure how much data is moving to a |
12 |
certain directory, and I want to compare it to what the adapter is |
13 |
supposed to do... (in some easy homeboy way). |
14 |
|
15 |
I vaguely remember something about 8 bits to a byte or maybe its the |
16 |
other way round... |
17 |
|
18 |
My homeboy transfer measurements: |
19 |
|
20 |
I measure the incoming MegaBytes as measured with `du' with a while |
21 |
loop interating in settable intervals. So in this case when set to 60 |
22 |
seconds,I now the number of megabytes that arrive in 60 seconds but |
23 |
would like to know how to convert that to the other notation. |
24 |
|
25 |
I'm seeing between 222 and 237 MB in a full minute being transferred |
26 |
and it seems quite slow for what is supposed to be a gigabyte network. |
27 |
|
28 |
This is just across two computers on my home lan, both with gigabyte |
29 |
adapters and they connect thru a gigabyte switch. Or I hope they are. |
30 |
|
31 |
My setup looks like this in brief (simplified). |
32 |
|
33 |
The transfer is between h4 and h5 (windows XP, windows 7) You'll note |
34 |
there is 10/100 router between the whole lan and the internet. |
35 |
|
36 |
Both of the subject machines are set to the 10/100 router as default |
37 |
route. The Gigabyte switch has no address. |
38 |
|
39 |
internet |
40 |
| |
41 |
| |
42 |
| |
43 |
(netgear router is lan `default route' <= 10/100***** |
44 |
NETGEAR ROUTER (inside address 192.168.0.20) |
45 |
| | | |
46 |
| | | |
47 |
(192.168.0.5) h1 | h3 (192.168.0.7) |
48 |
| |
49 |
| |
50 |
gigabyte switch |
51 |
| | |
52 |
| | |
53 |
(192.168.0.9) h4 h5 (192.168.0.17) |
54 |
|
55 |
So I guess I worked another whole subject into this but really I would |
56 |
like to know how to make the conversion mentioned. |
57 |
|
58 |
But also if I should be expecting h4 h5 to be able to use GigaByte |
59 |
transfer speeds. |
