sknks, when using a 10Mbps pcmcia network interface, the Network Utilisation (TaskMan) indicates increasing usage as i increase network traffic (downloads etc), all the way upto 88%. however, when using a 100Mbps interface, the same gets stuck at 0.47%, no matter how much traffic i push. networking gurus, anyone to shed some light on this? what / where / why is the bottleneck? <m.b> -- ------------------------------ <...global warming is a myth...> ------------------------------ [: +254 722 296 184 , +254 732 296 654 e: motobaridi@motobaridi.com

@Moto, the main reason for the above performance is due to the half duplex setting on pcmcia card while full duplex on the other one. The pcmcia card may have some backward compatiblity issues or an older type, thus the card has switched to half duplex. As a remedy, go into the card's properties and manually change settings to full if it allows it. HTHs.

0.47% or 4.7% ? 10 Mbps [Half-duplex ] = BW of 1 MB/sec 100 Mbps [Full-duplex] = BW of 20 MB/sec 88% of 1 MB/sec = 880 KB/sec (880KB/sec) / (20 MB/sec) = ~ 0.45 = 4.5% Where is your download source? The most accurate way to check your bandwidth is to transfer data to/from RAM between two machines, time the transfer and check the BW. There are an inordinately large number of tools out there what will do this for you.
...0.47% is correct... On Sat, Nov 14, 2009 at 8:38 PM, rsohan@gmail.com <rsohan@gmail.com> wrote:

What are you downloading, and from where? have you actually tried measuring the download speed using wall-clock time? On Mon, Nov 16, 2009 at 2:01 PM, MotoBaridi <motobaridi@gmail.com> wrote:
